Relief of excited-state antiaromaticity enables the smallest red emitter
H. Kim, W. Park, et al.
This groundbreaking research by Heechan Kim, Woojin Park, Younghun Kim, Michael Filatov, Cheol Ho Choi, and Dongwhan Lee reveals that low-energy electronic transitions can be achieved without large π-conjugated systems. The study introduces a novel class of light-emitting molecules based on diacetylphenylenediamine isomers, with *p*-DAPA standing out as the lightest known red emitter. Discover how modifying these molecules expands the visible spectrum of emitters!
