Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

open access: yesAdvanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...
