Abstract The understanding of the excited state dynamics thermally activated delayed fluorescence (TADF) materials is crucial. In this study, two donor–acceptor‐type TADF emitters with highly twisted conformation are synthesized. subtle chemical modification donor unit exhibit opposite aggregation luminescent behaviors: aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ). Through photophysical properties crystallographic analysis, theory simulations, it discovered that X‐aggregation supports AIE behavior by restricting intramolecular motions preserving via an efficient reverse intersystem crossing (RISC) process, but on other hand, H‐aggregation leads to ACQ due inhibited RISC, disabled channel, weak phosphorescence from radiative low‐lying triplet state. findings shed light excited‐state dynamic behaviors emitters, which dependent aggregation.

Most aggregation-induced emission (AIE) luminogens exhibit high brightness, excellent photostability, and good biocompatibility, but these AIE-active agents, which kill two birds with one stone to result in applications both stimulated depletion (STED) super-resolution imaging photodynamic therapy (PDT), have not been reported yet are urgently needed. To meet the requirements of STED nanoscopy PDT, D-A-π-A-D type DTPABT-HP is designed by tuning conjugated π spacers. It exhibits red-shifted emission, PLQY 32.04%, impressive 1O2 generation (9.24 fold compared RB) nanoparticles (NPs). Then, NPs applied cell via nanoscopy, especially visualizing dynamic changes lysosomes PDT process at ultrahigh resolution. After that, vivo was also conducted NPs, resulting significantly inhibited tumor growth, an inhibition rate 86%. The work here beneficial design multifunctional agents deep understanding their phototheranostic mechanism biological research.
