Abstract
- Thermally activated delayed fluorescence (TADF) emitters featuring through‐space charge transfer (TSCT) can be excellent candidates for piezochromic luminescent (PCL) materials due to their structural dynamics. Spatial donor‐acceptor (D−A) stacking arrangements enable the modulation of inter‐ and intramolecular D−A interactions, as well as spatial charge transfer states, under varying pressure conditions. Herein, we demonstrate an effective approach toward dynamic reversible full‐color PCL materials with TSCT‐TADF characteristics. Their single crystals exhibit a full‐color‐gamut PCL process spanning a range of 170 nm. Moreover, the TSCT‐TADF‐PCL emitters display a unity photoluminescence quantum yield, and show promising application in X‐ray scintillator imaging. [ABSTRACT FROM AUTHOR]
