MON | Oct. 12: RNA’s Evolution from an Eccentric Molecule to a New Class of Medicines
TUES | Oct. 13: Sequence-based Design of Small Molecules Targeting RNA – From Chemical Probes to Precision Medicines
Abstract:
WED | Oct. 14: Covalent Approaches to Study and Optimize Small Molecule—RNA Interactions
RNA has evolved from being viewed primarily as an intermediate between DNA and protein to being recognized as a functional biomolecule that can directly drive human disease and serve as a therapeutic target. RNA folds into complex structures, regulates gene expression, catalyzes chemical reactions, and participates in nearly every major biological process. These properties create opportunities to develop new medicines that act directly on RNA.
Across this lecture series, Dr. Disney will describe how discoveries in RNA biology have shaped our understanding of RNA as a drug target and how chemical biology can be used to identify and exploit disease-relevant RNA structures. His group’s work combines RNA structure and large-scale screening to define RNA–small molecule recognition principles and to identify ligandable RNA structures across the transcriptome. These approaches enable sequence-based design of small molecules that modulate RNA processing, including strategies that recruit endogenous ribonucleases to selectively degrade disease-causing RNAs.

Dr. Robert Gilliard (MIT) will present a student-Invited Inorganic Seminar on Wednesday, October 7 @ 11:30 AM in 2104 HCEM titled “Borenium Ions and More: A Coordination Chemistry Approach to the Design of Functional Materials”. Join us!
Seminar Flyer with ATM logo.

Abstract text: Recent advances in our laboratory have revealed that cationic boron-containing π-systems can serve as powerful platforms for the design of functional optical and electronic materials. This lecture will explore how the incorporation of boron into conjugated aromatic frameworks, combined with stabilization by strongly donating carbodicarbene ligands, enables access to molecular architectures that were previously considered too reactive for practical applications. Particular emphasis will be placed on the development of air- and photo-stable borenium ions that exhibit highly tunable photophysical properties, including efficient luminescence across the visible and near-infrared spectral regions. The discussion will highlight molecular design strategies that leverage boron-centered cationic character, BN-substitution, π-extension, ligand electronics, and counterion effects to modulate frontier molecular orbitals and narrow optical energy gaps. These approaches provide routes to materials that combine the desirable electronic characteristics of extended acenes and nanographenes with substantially enhanced environmental stability. The role of carbodicarbenes as exceptionally strong donor ligands will be examined as a key enabling factor for stabilizing highly electrophilic boron centers while simultaneously controlling excited-state behavior. Recent discoveries demonstrating thermochromism, aggregation-induced emission, exciton coupling, and counterion-directed ion-pair assembly will be discussed as emerging design principles for stimuli-responsive and emissive materials. If time permits, our latest advances in diazoborane chemistry will also be discussed.

A biography with a picture of Prof. Gilliard is also included as a sidebar.

Dr. Pentzer will host Dr. Karl Scheidt (Northwestern) for an Organic Seminar entitled "Designing Reactivity and Building Complexity through Chemical Synthesis" on Thursday, October 8th at 11:30 in 2104 CHEM. Join us!
Seminar flyer with TAM logo. Abstract text: Catalysis and complex molecule synthesis mutually reinforce discovery: new reactivity enables access to challenging targets, while complex molecules inspire synthetic innovation. This program develops transformations and design principles, from N-heterocyclic carbene (NHC) catalysis to total synthesis of bioactive natural products. The first part of this seminar describes single-electron NHC catalysis, which combines carbene catalysis with photoredox activation to transform acyl azolium intermediates into ketyl radicals. These radicals couple with transient open-shell partners, enabling modular synthesis of ketones directly from carboxylic acids. The second part presents the first synthesis and absolute structural determination of secaloside natural products, metabolites isolated from rye pollen with previously unconfirmed stereochemistry. Together, these studies demonstrate how innovative reactivity and strategic synthesis can solve challenging problems in molecular construction.

Dr. Shiliang Tian (Purdue) will present an inorganic seminar on Wednesday, September 23, at 11:30 am in CHEM 2104. Dr. Tian's seminar is titled “Visualizing Reactive Intermediates: Radical and High-Valent Chemistry Across Biological and Synthetic Catalysis” Join us!
abstract text: Controlling reactive radical and high-Valent metal intermediates is a central challenge in biological and synthetic catalysis. My group combines EPR spectroscopy, cryo-EM, and computational methods to characterize these fleeting species. First, I will show how substrate-triggered conformational changes regulate radical chemistry in adenosytcobalamin-dependent mutases. Cryo-EM and EPR reveal that domain motions gate Co(lll)-C bond homolysis and confine the resulting 5'-deoxyadenosyl radical, enabling efficient catalysis while limiting off-pathway damage. Second, I will describe EPR studies that identify transient Cu(II), Cu(III), Ni(III), and formal Ni(IV) intermediates during catalytic C-C bond formation, supporting radical-mediated oxidative addition and unconventional high-valent redox cycles. Together, these studies reveal shared principles for controlling high-energy chemistry across biological and synthetic systems.

Dr. Dong Hee Son is hosting a Physical Seminar (Tuesday, September 29th, at 11:30 am in CHEM 2104), featuring Dr. Danielle Hickey (Penn State). Dr. Hickey's seminar is titled “Understanding Atomic Structures and Transformations in Low-Dimensional Materials”. Join us!
Seminar flyer with ATM logo. Abstract text: Many of the fascinating properties of materials can be linked directly to their atomic structures. Therefore, understanding materials at the atomic scale is essential to designing new structures with emergent properties. This seminar will present strategies we are developing to extract information from complex materials, using atomic-resolution imaging and other electron microscopy techniques, coupled with artificial intelligence (Al) methods. In this work, we will highlight how synthetic conditions lead to atomic structures that can be tuned on the basis of atomic-scale understanding. The presentation will focus on several examples, including the analysis of heterogeneities and structural transformations in inorganic nanocrystals, understanding defects in the stacking of two-dimensional (2D) layered materials, and the formation pathway and unique defects in quasi-1D materials.

Dr. Konstantin Bukhryakov (Florida International University) will present an Inorganic Seminar on Wednesday, September 30, at 11:30 AM in 2104 CHEM. The title of his seminar is Vanadium for Olefin Metathesis. Join us!
Seminar flyer with abstract text: Olefin metathesis is a widely used method for the production of chemicals used in daily life. The current production of fine and commodity chemicals via olefin metathesis relies on catalysts based on 2nd- and 3rd-row transition metals, such as Mo, Ru, W, and Re. The use of Earth-abundant first-row metals, such as V, will have a broad impact by providing less expensive, greener alternatives to existing methods. This, in turn, will make essential chemicals more accessible to consumers and decrease the human environmental footprint. Sustainability, low cost, and environmental preservation are essential, but not the only driving forces of our research. Thus, V-based catalysts can exhibit unique reactivity compared to second- and third-row counterparts. Specifically, V enables carbon isotope exchange directly on a target molecule containing terminal alkenes, which can be used for drug development.

Dr. Dong Hee Son and Dr. Arkajit Mandal are hosting a Physical Seminar (Tuesday, September 22nd, at 11:30 am in CHEM 2104), featuring Dr. Oleg Prezhdo of University of New Mexico. Dr. Prezhdo's seminar is titled “Quantum Dynamics in Optoelectronic Materials”. Join us!
Seminar flyer with ATM logo and abstract.
Modern applications involve far-from equilibrium processes occurring in condensed phase, nanoscale, molecular and hybrid materials. Examples include optoelectronic devices, solar cells, quantum information, batteries, detectors, memories, energetic materials, biomedical systems. Our theoretical methodology, combining real-time DFT with non-adiabatic molecular dynamics and machine learning, allows us to model non-equilibrium response in time-domain and at atomistic level, as it occurs in nature. Understanding and controlling modern systems create challenges due to differences between molecular and periodic, organic and inorganic matter, and multiple processes, including charge and energy transport, excitonic, plasmonic and polaritonic excitations, charge-charge and charge-phonon scattering, quantum coherence, etc. We provide a unifying description of quantum dynamics, characterize timescales and branching of competing processes, and generate guidelines for novel applications.

Professor Joya Cooley at California State University will be giving her Inorganic Division Seminar: Composition-Driven Control of Thermal Expansion in Metal Oxides on Thursday, September 24 at 11:30 AM (CT) in CHEM 2104. Join us!
Seminar flyer with ATM logo and abstract text: Thermal expansion describes how material dimensions change with temperature. Conventionally, materials expand when temperature is increased, but some materials exhibit negative thermal expansion (NTE). Control can be achieved in bulk materials when PTE and NTE materials are composited and the thermal expansion of the final material is tuned; in order to allow for tuning, understanding tunability of thermal expansion on an atomic level is key. NTE has been observed above 400 C in several transition metaloxides with the general formula A2Q2O7 (A = divalent metal, Q = P, V). This presentation will discuss efforts to rigorously characterize the thermal expansion behavior of some of these materials across length scales to control thermal expansion through compositional tuning.
Biographical text in sidebar: Joya Cooley (she/her) is an Associate Professor in the Department of Chemistry and  Biochemistry  at California State University, Fullerton. She earned a B.S. in Chemistry and a B.A. in Music from Furman University in Greenville, SC.

Dr Gabbai is hosting Dr. Alexandra Velian from the University of Washington, to present her seminar “Molecular Catalysts Go Nano: Installing Active Sites on Clusters and Nanosheets” on Wednesday, April 29 in CHEM 2104 at 11:30 AM.
Seminar Flyer with ATM logo and headshot of Dr. Velian.

Abstract text: A central research goal in the Velian group is to create next-generation single-atom catalysts that harness cooperativity between the active site and chemically non-innocent supports. To emulate defect sites in inorganic heterogeneous catalysts in a controlled fashion, we embed well-defined active sites on clusters and two-dimensional nanosheets.
The first part of this seminar will introduce a class of atomically precise nanoclusters featuring discrete active sites that dynamically engage with the metal chalcogenide support and with substrates.
The second part will present an orthogonal approach to catalyst design, where principles of organometallic phosphine chemistry are used to anchor single-site active centers on two-dimensional black phosphorus nanosheets. Molecular synthetic and characterization strategies are used to probe bonding and functionality.

Biography: Alexandra Velian began her independent career at the University of Washington in 2017. Her group studies single-site catalysts anchored on atomically precise metal chalcogenide clusters and on black phosphorus, with an emphasis	on	active site/support cooperativity.
Her work has been recognized with awards including a Sloan Fellowship (2024), a Camille Dreyfus Teacher Scholar Award (2023), the Marion Milligan Mason Award (2023), a Cottrell Scholar Fellowship (2020), and the Inorganic Chemistry Lectureship Award (2023).
She earned her B.S. at Caltech with Theodor Agapie and her Ph.D. at MIT with Christopher Cummins, where she studied reactive phosphorus species. She was a postdoctoral fellow at Columbia University with Colin Nuckolls.

Seminar flyer with ATM logo and headshot of Dr. Greenbert.
Abstract text: DNA-protein cross-links (DPCs) are highly toxic lesions formed via a variety of chemical pathways and as intermediates in enzyme transformations. DPCs are potent blocks of helicases, as well as DNA and RNA polymerases. DPCs are associated with aging and diseases such as cancer. Recently, DPCs were also shown to result in chronic inflammation. Despite their importance, our understanding of DPCs has lagged that of other forms of DNA damage. For instance, the first protease identified to repair DPCs in human cells (SPRTN) was only identified in the past decade. Our group is developing chemical tools for producing DPCs. These tools are useful for studying DPCs extra- and intracellularly, and are potentially useful pharmacologically. Recent published and unpublished investigations will be presented.
Biography: Marc Greenberg received his B.S. (Chemistry) from New York University and B.E. (Chemical Engineering) from The Cooper Union School of Engineering in 1982. After receiving his Ph.D. from Yale University in 1988 under the guidance of Professor Jerome Berson, he carried out postdoctoral research as an American Cancer Society fellow with Professor Peter Dervan at the California Institute of Technology. He began his independent career in 1990 at Colorado State University and moved to Johns Hopkins University in 2002 where he is the Vernon K. Krieble Professor of Chemistry. His research interests encompass fundamental and applied studies on nucleic acid chemistry and biochemistry.

Dr. Son will host a Special Physical Seminar next week, on Tuesday, April 28th, at 4pm in 2101 CHEM, featuring Dr. Tak W. Kee of Adelaide University. Dr. Kee's seminar is titled, "Ultrafast Singlet and Triplet Exciton Dissociation in Organic Photo-Catalysts for Hydrogen Generation".
Seminar flyer with ATM logo and picture of Dr. Kee in front of a maroon background.
Abstract: Hydrogen gas is an important energy source that attracts significant attention due to its zero-carbon emission. Current methods of producing H2, which are powered by fossil fuels, release a high level of CO2. A cost-effective and green alternative to current methods is photocatalytic H2 evolution using nanoparticles of organic semiconductors. Typically, this process uses light to generate singlet excitons, which then undergo exciton dissociation at interfaces between electron donor and acceptor materials. The generated charges upon exciton dissociation can migrate to the photocatalyst’s surface to facilitate proton reduction to form H2. We use broadband ultrafast transient absorption spectroscopy to study singlet exciton dissociation to form charge carriers with a time resolution of ~10 fs. We find that exciton dissociation occurs with time constants ranging from 28 - 149 fs. Ultrafast exciton dissociation correlates with the morphology of the photocatalyst. The presence of mixed H/J aggregations increases energetic disorder to promote ultrafast exciton dissociation. Our results indicate that exciton dissociation occurs at sufficiently high rates to outcompete most other photophysical processes in the photocatalyst. I will also discuss a novel approach of using triplet energy transfer to generate triplet excitons of an organic semiconductor to increase the efficiency of H2 evolution. Triplet excitons are longer-lived species than singlet excitons due to their spin-forbidden relaxation to the ground state. As a result, the longer triplet exciton lifetime may allow a higher probability for charge separation than that using singlet excitons. The use of triplets could pave the way for singlet fission, a process that converts a singlet into two triplets, to be explored for maximizing the efficiency of H2 evolution in organic semiconductors.

Dr. Dia Das from Southern Methodist University will be visiting the department on Thursday, April 23rd, and will be giving a seminar at 11:30 am in 2104 CHEM entitled "Tuning Atomically Precise Materials for Sustainable Chemistry." Join us!
Seminar flyer with ATM logo and picture of Dr. Das.

An abstract is included with the following text: With the advent of nanotechnology in the mid-1980s, nanomaterials have attracted tremendous interest due to their unique properties which make them suitable for diverse applications. However, the inherent polydispersity of conventional nanoparticles has precluded an atomic-level understanding of their structure-property relationships. This, in turn, has greatly hampered the complete realization of their target functional properties in real-world applications. This talk will focus on leveraging the principles of synthetic organic and inorganic chemistry to engineer multifunctional atomically precise materials for applications in catalysis, water harvesting, and iodine capture. Specifically, we will discuss two classes of materials, (1) molecularly pure, ligand-protected coinage metal clusters, and (2) covalent organic frameworks (COFs), which are atomically precise tunable materials with extraordinary porosity and crystallinity. Overall, these efforts aim to establish design rules for making functional heterogeneous nanomaterials with known structure-property-function relationships.

Biography: Anindita (Dia) Das obtained her Ph.D. with Prof. Rongchao Jin at Carnegie Mellon University, where her research focused on the synthesis and single-crystal growth of atomically precise gold nanoparticles to gain in-depth understanding of catalytic mechanisms. Prior to this, she earned B.Sc. and M.Sc. degrees at Osmania University, India and the University of Pune, India respectively. Following her PhD., Dia carried out postdoctoral research with Prof. Chad Mirkin at Northwestern University, where her work centered on the development of spherical nucleic acids based on atomically precise gold nanoclusters for applications in colloidal crystal engineering. Dia started her independent lab in the Chemistry Department at Southern Methodist University in Fall 2020.

Abstract text: Natural products continue to inspire medicine, agriculture, and chemical biology through their remarkable structural diversity and biological activities. The biosynthesis of these molecules often relies on enzymes that catalyze chemically challenging transformations, yet how such unusual chemistry is programmed and controlled by proteins remains incompletely understood. In this seminar, I will describe our efforts to decode the unusual chemical logic of natural product biosynthesis and to harness biosynthetic enzymes as platforms for biocatalysis, including the discovery of unusual enzymes from the biosynthetic pathways of trichothecene, swainsonine, and loline alkaloids; as well as the reprograming of pyridoxal 5'-phosphate -dependent enzymes for [3+2] annulation reactions. Together, this work highlights how understanding natural product biosynthesis can enable both discovery of new bioactive compounds and the development of programmable biocatalysts for synthetic applications.

Dr. Adrian Figg from Virginia Tech, hosted by Dr. Emily Pentzer, is visiting this week as part of the Organic Seminar Series. His talk, titled "Approaching Acrylic Copolymer Structures Differently," is on THURSDAY at 11:30 am in CHEM 2104. Join us!
Seminar flyer with ATM logo an headshot of Dr. Figg. An abstract is included. Abstract text: Controlled polymerization techniques (e.g., reversible addition-fragmentation chain transfer (RAFT) polymerization) provide access to defined copolymer structures where block sequence, monomer composition, and architecture can be readily tuned. Herein, syntheses approaches will be introduced that take advantage of photoinduced electron/energy transfer (PET) catalysis to control mechanisms of radical introduction. For example, we developed synthetic methods to yield polymers containing more precise control over monomer placement and sequence. Additionally, new ways of interfacing acrylic copolymers with proteins to modulation functions show that copolymer composition is critical to achieve protein recognition. Overall, new synthetic design considerations for acrylic copolymers using RAFT polymerization will be discussed.

Professor Brandi Cossairt at University of Washington gives the Inorganic Division Seminar: Precision Synthesis and Deterministic Placement of Quantum Light Technologies April 8 at 11:30 AM in room 2104 CHEM. Join us!
seminar flyer with ATM logo and headshot of Dr. Cossairt.
Abstract text: Realizing scalable quantum light technologies requires both atomically precise nanocrystal synthesis and deterministic single-particle positioning. This talk explores strategies to achieve these goals by leveraging the extremes of nanocrystal size. First, we examine kinetically persistent cluster molecules, which are intermediates in colloidal nanocrystal nucleation, as high-fidelity models for understanding crystal growth mechanisms, structure, and reactivity. By understanding the structure, formation, and conversion of these clusters, we gain insights into synthesis pathways that minimize ensemble heterogeneity and move us toward the chemist's dream of perfect nanocrystals. Next, we address a critical challenge in quantum photonics: the scalable integration of colloidal quantum dots as single-photon emitters. We demonstrate two approaches that exploit QD size to enable deterministic placement into large-scale ordered arrays while preserving photostability and quantum emission properties. Specifically, SiO2 and CdS shells expand QD size, facilitating precise positioning via high-fidelity template-assisted self-assembly and electrohydrodynamic inkjet printing. We show that single “colossal” QDs maintain room-temperature antibunching behavior and can be deterministically coupled to photonic cavities, advancing their viability for quantum technologies.

Dr. Son and Dr. Altman are hosting a Physical and Inorganic Seminar today, at 11:30 AM in CHEM 2104, featuring Dr. Dmitri Talapin of the University of Chicago. Dr. Talapin's seminar is titled, "Exploring Different Intersections of Solid-State and Molecular Chemistry".
Seminar flyer with headshot of Dr. Talapin and abstract.
Abstract text: Low-dimensional materials, including nanocrystals and atomically thin two-dimensional sheets, effectively bridge the gap between bulk solids and molecules. These materials have advanced significantly in recent years, largely due to their potential for real-world applications. I will discuss the integration of concepts from solid-state chemistry, molecular chemistry, and nanotechnology toward development of novel functional materials.
For example, we expanded the range of synthesizable quantum dots by developing a new class of colloidal systems-colloids in molten inorganic salts. Using molten salts, we successfully synthesized the first colloidal emissive GaAs and GaN quantum dots, as well as various other functional nanomaterials previously dubbed impossible to synthesize by colloidal methods.
In another example, we combined principles from solid­ state and molecular chemistry to advance two­ dimensional transition metal carbides and nitrides, known as MXenes. These materials combine the robust electronic and mechanical properties of inorganic 20 crystals with nearly limitless molecular engineering of their surface chemistry. Understanding MXene surfaces requires concepts from coordination chemistry, self­ assembled monolayers, and surface science. We demonstrate that MXene surfaces actively contribute to the materials' conductivity, superconductivity, and catalytic activity.

While powerful, this focus implicitly treats activation as the primary objective of chemical innovation. In this talk, I argue for a broader perspective based on isoreactivity, in which elementary steps and their relationships, rather than modes of activation, form the fundamental organ1z1ng principle. lsoreactivity describes contexts where distinct sub-structures in elementary steps can be replaced while maintaining elementary step viability. More broadly, this perspective points toward an organizing framework for chemical reactions grounded in recurring patterns across elementary steps.

Seminar flyer that includes the abstract: Cells and tissues exhibit biological heterogeneity that underlies their functions and responses to environmental exposures. Elucidating the spatial molecular landscape of heterogeneous biological systems represents a frontier in biological research. Mass spectrometry imaging (MSI) represents a powerful toolkit to map the spatial distribution of elements and molecules in situ, leveraging both spatial resolution and molecular and elemental specificity. Our lab applies MSI, primarily matrix­ assisted laser desorption/ionization (MALDl)-MS, to characterize spatial chemical landscapes in host­ microbe systems and map toxicity responses in tissues. In this seminar, I will describe our recent work in mapping metabolites in mouse colon and nematode Caenorhabditis elegans, as well as enabling fast and in-situ analysis of per- and polyfluoroalkyl substances (PFAS), a class of emerging environmental contaminants, using MALDI-MS coupled with trapped ion mobility spectrometry (TlMS).

Dr. Blanton Tolbert from the University of Pennsylvania will be visiting the department Monday, March 30th to give a seminar titled "From Recognition to Regulation - Allostery in RNA-Protein Networks" at 11:30 a.m. in CHEM 2104. Join us!
seminar with abstract text
Gene expression is governed by a dense network of heterotypic RNA-protein (RNP) interactions, yet the principles that dictate how functional RNP assemblies form and regulate biological outcomes remain poorly defined across much of the transcriptome. A major obstacle is the intrinsic heterogeneity of these interactions, which complicates efforts to extract generalizable rules from genome-wide studies. In this seminar, I will introduce mutual allostery as a conceptual framework for understanding how RNA and protein components cooperatively encode regulatory control. Allostery is traditionally viewed as communication between distant sites within a macromolecule; here, the concept is extended to heterotypic RNPs, where reciprocal coupling between RNA and protein conformational states shapes assembly, specificity, and function. Through selected examples, I will illustrate how allosteric communication across RNP interfaces can influence higher-order complex formation and regulatory outcomes. Together, these observations support the idea that mutual allostery may represent a unifying mechanism by which heterotypic interactions modulate RNA biology. More broadly, this framework suggests new ways to think about, and ultimately manipulate, RNA-centered regulatory systems using chemical principles.

Biographical information is also included: Blanton S. Tolbert, PhD, is the Jacob Gershon-Cohen Professor of Biochemistry and Biophysics at the University of Pennsylvania, where he leads a research program investigating RNA virus biology and virus–host interactions, with emphasis on protein–RNA complexes as therapeutic targets.

Dr. Joshua Buss of the University of Michigan will present his seminar, "Mapping Surface Science Mechanisms with Atomic Precision" at 12:30 pm in CHEM 2104 on Wednesday, April 1. Join us!
Seminar flyer with abstract text: The most important global chemical processes rely on multimetallic catalysts that facilitate difficult bond making and bond breaking transformations. Many of these catalysts take the form of evolutionarily optimized enzymatic machinery, while equally vital are engineered heterogeneous catalysts used in large-scale industrial chemical transformations. A significant challenge in
optimizing existing catalysts and discovering or designing new ones Is the lack of fundamental mechanistic understanding of the elementary chemical processes taking place at the active site. My research group addresses this knowledge gap by employing inorganic synthesis to prepare and study multimetalllc complexes that adopt design features prevalent in both industrial and enzymatic catalysis. This talk will describe the synthesis of an unusual, low-valent multicopper cluster that serves as a soluble fragment of crystalline Cu(111). Studies investigating small molecule binding and activation, as they pertain to substrate adsorption and chemisorption, are presented. This platform also facilitates surface-like catalytic transformations of NO, reagents, unsaturated hydrocarbons, and carbon oxygenates. These chemistries, including Insights Into their respective mechanisms, will be compared to prevailing mechanistic proposals In surface science.

Seminar flyer with abstract text: This seminar will present molecular design strategies that enhance polyester degradation through main-chain modification. First, insights from the marine biodegradation of discrete poly(butylene succinate) oligomers are used to guide the design of polyesters containing periodically cleavable main-chain linkages. Second, heteroatom substitution in polyester backbones is achieved via ring-opening copolymerization and step-growth polymerization, introducing sulfur-containing thionoester or thioester linkages that promote backbone cleavage under specific conditions. Together, these studies illustrate how backbone modification can improve degradation behavior and provide general strategies for designing degradable polyesters.

Seminar flyer with abstract text: Macrocyclic arene compounds have played a fundamental role in the development of supramolecular chemistry. Research on these systems have laid the foundations to explore and establish non-covalent interactions, e.g., hydrogen bonding, TT···TT stacking, C-H·•·TT interactions. My research group has taken the basic principles of macrocyclic arenes to design architectures enforcing metal-metal interactions towards the activation of small molecules, scaffolds capable of tubularly contorting aromatic systems, and frameworks able to bind anionic species for environmental remediation, all while retaining their intrinsic non-covalent interactions. In this seminar, I will discuss our progress in each of these areas constantly crossing the boundaries between organic-inorganic synthesis and materials chemistry.

seminar flyer with abstract text: A launch-point for potentially transformative materials is the synthetic design of polymer microstructures capable of offering precise and unique functional sequencing outside of those provided by traditional monomers and methods. The concept of using low ring strain cycloolefin monomers, such as cyclopentenes, for enthalpy-driven ring-opening metathesis polymerization (ROMP) is contradictory since the release of ring-strain is the driving force for success. Our research has leveraged thermodynamic principles to gain near living-like control and high conversion from these systems. We have now carried this success forward to instill more precise architectural complexities such as highly isotactic and regioregular systems, fluorine-free fuel cell membranes, and bottlebrush polymers with precise functional branch periodicities. We have also carried some of these strategies over to biomass-based terpene derivates. Our findings on the efficacy of targeted materials, their properties and outlook will be discussed.

seminar flyer
abstract text: Atmospheric N2 is a cheap, abundant resource with great potential for energy storage and chemical synthesis, but it is difficult to convert it into other compounds ("fixing" nitrogen). This seminar will describe the challenges and opportunities of nitrogen fixation, as well as my students' discoveries of how to break the N–N bond of N2 using homogeneous transition-metal complexes. In addition to new catalysts for producing ammonia, we have identified a new mechanism for sequential C-H activation and N-N activation to create C-N bonds. Detailed mechanistic studies reveal a cyclic reaction, which gives a route from atmospheric N2 and petroleum-derived arenes to substituted anilines. This is an important step toward preparing useful chemicals using air as a starting material.

Flyer for Frontiers Seminar with picture of Dr. Chirik in a building with windows. Included is an abstract and some information about the lecture series.
Abstract Text
How chemists interact with and ultimately use the elements on the periodic table is one of the primary sustainability challenges of the 21st century. Applications ranging from alternative energy to catalysis to sustainable plastics need to rely on Earth abundant elements such as iron rather than terrestrially rare ones that have a large environmental footprint associated with mining, purification and recovery. Our research group is exploring the new chemistry enabled by catalysis with earth- abundant transition metals. Motivations are two-fold. First, we strive to discover highly effective catalysts with applications in the pharmaceutical, flavor and fragrance, silicones, energy and polymer science industries. Second, we seek to uncover the unique pathways that enable these transformations, many of which are distinct from precious metals. An emphasis in my lectures will be the fundamental organometallic chemistry of open-shell first-row metal complexes, how to control spin and one-electron redox to impart new reaction chemistry as well as the distinct mechanisms that underly these catalytic transformations.

 THE FRONTIERS IN CHEMICAL RESEARCH DISTINGUISHED LECTURE SERIES features in-depth presentations of current developments in important areas of contemporary chemistry from prominent chemists of international renown who are describing their most recent significant research results. In addition to delivering three seminars, each Frontiers speaker interacts with graduate students and departmental instructional and research staff in formal discussion sessions and meetings.

Dr. Brandon Rotavera (Georgia) will present a seminar “Chemical Kinetics of Cyclic Ethers in Combustion”. on Tuesday, November 25 in CHEM 2104 at 11:30 AM. Please join us!
seminar flyer with ATM logo
Accurate description of the chemical kinetics of cyclic ethers is critical to addressing mechanism truncation error. The presentation discusses ongoing efforts to produce high-fidelity sub-mechanisms for cyclic ethers isomers relevant to low-temperature combustion. The approach involves isomer-resolved speciation measurements from gas-phase oxidation experiments in a jet-stirred reactor coupled with high-level quantum-chemical computation of rate coefficients and thermochemical properties of species. Alkyl-substituted cyclic ethers including alkyloxiranes and alkyloxetanes are isomer-specific proxies for reaction mechanisms of carbon-centered hydroperoxyalkyl radicals (Q̇OOH). Subsequent bimolecular reactions of cyclic ethers include H-abstraction, which creates strained, carbon-centered radicals that may form peroxy radicals following O2-addition or may proceed via non-Boltzmann-type reactions wherein rovibrationally excited radicals undergo prompt ring-opening prior to collisional stabilization. In addition, stereochemical effects, namely the position of the substituents relative to the plane of the ether group, creates stereoisomer-specific reaction pathways; some involving chain-branching via formation and decomposition of organic acids (e.g. performic acid) and some involving the formation of metastable dicarbonyls (e.g. 2,4-pentanedione) conventionally ascribed to decomposition of ketohydroperoxides from Q̇OOH + O2.
