Abstract Significant advances are made in understanding the structure‐property relationship room‐temperature phosphorescence (RTP) materials. For example, intramolecular charge transfer (ICT) structural molecules based on electron donors(D) and acceptors(A) an efficient method to achieve RTP. However, ability precisely regulate singlet‐triplet energy gap (Δ E ST ) through molecular design control RTP emissions remains constrained. Herein, a group of 4BN‐NP 5BN‐NP isomers is reported with D A position isomerization, where exhibits photo‐induced orange afterglow phenomenon PMMA. Calculations show that spin‐orbit coupling (SOC) value greater compared intersystem crossing (ISC) channel more efficient, resulting smaller Δ for . This indicates short ICT conducive inducing emission. In addition, compound co‐doped red fluorescent dyes (RhB, Rh6G, RBNN) PMMA produces resonance (PRET), Surprisingly, light‐activated yellow can be obtained by attaching polymethyl methacrylate (PMMA) nylon filaments, its intensity does not diminish even when it immersed water containing detergent solution, thus expanding prospects application textile encryption.

Ultralong room-temperature phosphorescence (URTP) materials have been widely studied due to their broad applications. However, achieving phosphorescent with ultralong lifetimes is engaging and challenging. In this work, the indolo[3,2,1-j,k]carbazole (ICZ) excellent planarity obtained through twice single-bond locking on triphenylamine (TPA). Doping ICZ into a rigid matrix, URTP lifetime of 3.24 s photoluminescence quantum yield 37.37% successfully prepared.. The analysis single-crystal, temperature-dependent photophysical characterization, Huang–Rhys factor, theoretical calculations demonstrates that it possible make molecules more planar by locking, which can inhibit structural relaxation excited state thus reduce nonradiative transition generate URTP. addition, we achieve full-color afterglow energy transfer. potential applications anticounterfeiting optoelectronic information display these conducted. This work an important reference for construction materials.
