Molecular switches—compounds capable of reversibly interconverting between distinct states in response to external stimuli—are foundational to the design of dynamic functional materials. Classical…

In 1972, Erich Clar envisioned Clar’s goblet, a polycyclic aromatic hydrocarbon featuring two unpaired electrons that are spin-paired. However, synthesizing it in a solution phase remains challenging....

We report a highly contorted phosphaquinoid by substituting one of the exocyclic C [[double bond, length as m-dash]] C bonds of an anthraquinodimethane unit with a phosphaalkene unit (–C [[double bond...

Thioxanthone synthesis from o-silylaryl triflates and thioureas is disclosed. Double aryne insertion into the C═S double bond of thioureas and subsequent hydrolysis realized the facile preparation of ...

This experimental and theoretical study illustrates how phosphaalkenes, which are isolobal to alkenes, can utilize a variety of external triggers for molecular switching. The E/Z isomerization of a t...

The potassium aluminyl K[Al(NON)] ([NON]2– = [O(SiMe2NDipp)2]2–, Dipp = 2,6-iPr2C6H3) reacts with group 14 chloroamidinates E{14}(Am)Cl (E{14} = Ge, Sn, Pb. [Am]– = [tBuC(NDipp)2]–) to form (NON)Al–E....

In this study, we present the synthesis and analysis of a novel, air-stable, and solvent-resistant phosphaalkene switch. Using this symmetric switch, we have demonstrated degenerate photoisomerizatio...

In situ 1D NMR spectroscopic reaction monitoring allows detailed investigation of chemical kinetics and mechanism. Concentration versus time data are derived from a time series of NMR spectra. Each sp...

Antiaromatic rings are infamously unstable and difficult to work with but they possess unusual electronic properties that make them interesting for fundamental and applied research. This perspective p...

By employing an anthracene-based secondary phosphine as a synthon, a straightforward and high-yielding synthetic method for P-doped overcrowded ethylenes (OCEs) of the Thiele's hydrocarbon family is ....

The sequential single-electron reduction of a truxene-based triphosphaalkene afforded mono-, di-, and triradical anionic species. X-ray crystallography revealed a highly contorted truxene core in the....
