Aggregation-Controlled Triplet Exciton Regulation Enables Single-Emitter Color-Evolving Afterglow. [PDF]

Adv Sci (Weinh)
A single‐emitter system based on DTP‐R luminophores enables time‐evolving afterglow through aggregation‐regulated excited‐state dynamics. The coexistence and suppression of delayed fluorescence and phosphorescence are controlled via concentration tuning and host‐guest engineering, revealing the RISC origin of delayed fluorescence and enabling ...
