Enhanced blue TADF in D-A-D type naphthyridine derivative with asymmetric carbazole-donor motif

Efficient triplet-to-singlet conversion in conventional donor-acceptor TADF compounds relies on charge-transfer (CT) and locally-excited (LE) triplet state mixing as this provides required spin-orbit coupling. In this work, asymmetric carbazole-donor motif...

From fluorogen to fluorophore by elucidation and suppression of ultrafast excited state processes of a Schiff base

Strategies have been explored for developing strongly fluorescent species out of a weakly fluorescent Schiff base, 2-(((pyridin-2-ylmethyl)imino)methyl)phenol (salampy). The locally excited enolic state of salampy undergoes an intramolecular proton transfer...
