Recently, organic room-temperature phosphorescence (RTP) materials, especially those with reversible responses to external stimuli, have attracted extensive attention. A dynamic regulation strategy enables the materials to rapidly respond to external stimuli, gifting varied RTP performance and greater application potential in sensitive sensing, detection, and so on. For these reasons, this Review summarizes progress in the regulation of dynamic RTP in recent years. It focuses on physical regulatory factors including light, heat, and mechanical force as well as chemical regulatory factors including water, pH, and oxygen. It is expected to be beneficial for developing smart materials with dynamic RTP in the future.

“…Organic room-temperature phosphorescent (RTP) materials have gained remarkable attention due to their vast potential as optoelectronic, anticounterfeiting label, − sensing, , and bioimaging devices. , To date, considerable endeavors have been undertaken to craft highly efficient RTP materials. Yet, despite advancements in the field, most available materials predominantly emit colors from cyan to orange, − with those producing deep-red to NIR emissions being conspicuously limited. The development of RTP materials with NIR emission inherently requires lowering of the lowest triplet (T1) energy level.…”

Organic cocrystals obtained from multicomponent self-assembly have garnered considerable attention due to their distinct phosphorescence properties and broad applications. Yet, there have been limited reports on cocrystal systems that showcase efficient deep-red to near-infrared (NIR) charge-transfer (CT) phosphorescence. Furthermore, effective strategies to modulate the emission pathways of both fluorescence and phosphorescence remain underexplored. In this work, we dedicated our work to four distinct self-assembled cocrystals called “pyrene box” cages using 1,3,6,8-pyrenetetrasulfonate anions (PTS 4– ), 4-iodoaniline (1), guanidinium (G + ), diaminoguanidinium (A 2 G + ), and hydrated K + countercations. The binding of such cations to PTS 4– platforms adaptively modulates their supramolecular stacking self-assembly with guest molecules 1, allowing to steer the fluorescence and phosphorescence pathways. Notably, the confinement of guest molecule 1 within “pyrene box” PTSK{1} and PTSG{1} cages leads to an efficient deep-red to NIR CT phosphorescence emission. The addition of fuming gases like triethylamine and HCl allows reversible pH modulations of guest binding, which in turn induce a reversible transition of the “pyrene box” cage between fluorescence and phosphorescence states. This capability was further illustrated through a proof-of-concept demonstration in shrimp freshness detection. Our findings not only lay a foundation for future supramolecular designs leveraging weak intermolecular host–guest interactions to engineer excited states in interacting chromophores but also broaden the prospective applications of room-temperature phosphorescence materials in food safety detection.
