Interested in non-functional organic magnetic switches? We actually do want to make them work — that’s why we study the ones that don’t, so we can make them function :-) Check out our new preprint 🔗 chemrxiv.org/engage/chemr... @paulinepfister.bsky.social @chem.uzh.ch #ChemSky #PiSky

Fluoranthene-Containing Distorted Nanographenes Exhibiting Two-Photon Absorption Response
Two distorted nanographenes combining helicenes and a fluoranthene unit within their polycyclic scaffolds were synthesized. Their structural and electronic properties were elucidated by various spectr...

Super stoked about our second JACS! We establish allenes as reversible halochromes with dramatic optical property switching. This work could not have been this successful without the amazing support from @minjungson.bsky.social at BU and the Ding Lab at WFU. Check it out pubs.acs.org/doi/10.1021/...

Allenes as Stimuli-Responsive Chromophores for Visible to Near-Infrared Optical Modulation
Despite their rigid, orthogonal π-systems and synthetic modularity, allenes remain underexplored in functional material design. Here, we report that tetraaryl-substituted allenes undergo clean and rev...

Water impacts self-assembly. But what changes really? In our latest @jacs.acspublications.org at 🇨🇭UNIGE, we ferret out vastly different organisations in wet vs dry solvents that lead to identical macrostructures 👉 doi.org/10.1021/jacs.4c17024 #pisky #chemsky @rickhauslab.bsky.social

A Supramolecular Nanosheet Assembled from Carpyridines and Water
The use of water as a solvent to facilitate supramolecular self-assembly and polymerization is well-documented; however, it is rare that water acts as a monomer that undergoes polymerization. We repor...

Our new preprint introduces a new approach for controlling the helicity and handedness of polyaromatics using a helical cyclophane synthon: isobenzofuranophane. We demonstrate the applicability by remotely controlling the handedness and pitch of [5]helicenes. go.shr.lc/44yCyln #PiSky

An ABSOLUTELY spectacular structure by the Xia group at SUSTECH. Haiping & his team have been working on enveloping the metal with a fully conjugated carbon ring for over a decade, and they finally succeeded! This warms my reformed metallabenzene chemist's heart! cen.acs.org/synthesis/Os... #PiSky
