We report a multi-resonant thermally activated delayed fluorescent (MRTADF) afterglow emitter with unprecedented long emission lifetime > 100 ms, full-width at half-maximum < 40 nm, and deep-blue color of CIEy 0.048. Such emitters remain rarely achieved would show potential applications in multiplexed bioimaging high-density information encryption.

Abstract Blue afterglow constitutes of one the primary colors and can convert into other through energy transfer. The reported studies show fabrication blue emitters, but most them are formed by room‐temperature phosphorescence mechanism require UVB lights as excitation source (these high‐energy may damage organic systems). Here we report visible‐light‐excitable thermally activated delayed fluorescence type (TADF‐type) materials via delicate control excited states in difluoroboron β‐diketonate (BF 2 bdk) systems. Tiny change substituents BF bdk system has been found to pose significant influence on state levels consequently narrow singlet‐triplet splitting system. As a result, both forward reverse intersystem crossing have accelerated, leading emergence bdk's TADF‐type rigid crystalline matrices. resultant exhibit emission lifetimes several hundred milliseconds, photoluminescence quantum yield (PLQY) 24.7 % display temperature responsive property.
