Supramolecular organogels have emerged as a promising matrix for achieving dynamic room-temperature phosphorescence (RTP) due to their rigid three-dimensional network structure, sensitive responsive behavior external stimuli, and perfect reversibility. However, the efficient construction of single-component, ultralong organic RTP materials remains significant challenge.

Abstract Blue is one of the three primary colors, and it a crucial element in regulation application organic room‐temperature phosphorescence (ORTP). However, considerable Stokes shift small molecules presents challenge for creating blue afterglow materials. To address this, host‐guest‐doped materials are prepared by selecting compounds with similar structures self‐doping. This method effectively regulated long‐lasting phosphorescence. Additionally, persistent‐RTP long‐persistent luminescence (LPL) properties can be further enhanced incorporating rigid or flexible polymer network, dense environment between host guest. Remarkably, lifetime duration polymer‐assisted doped ≈5 times greater than those host‐guest crystal Apart from its high efficiency, environmental friendliness, easy synthesis, this ORTP material boasts thermal stability flexibility. Furthermore, demonstrates potential applications such as information encryption anti‐counterfeiting across various media, including paper, cotton thread, leaves.

Abstract In recent years, there is a growing interest in developing ultralong organic room‐temperature phosphorescence (ORTP) with lifetimes the range of seconds. As one important three primary colors, blue ORTP an indispensable core component RTP regulation and application, however, large Stokes shift characteristics pose certain challenges ORTP. Here, new family phosphors are synthesized realized through crystal assembly water phase. Remarkably, compared to materials obtained phases, enabled long‐lived up 2.3 s quantum yield reached as high 29.27%. addition efficient green form, such dark possessed thermal stability flexible tunability. Moreover, superiority selected components demonstrated by comparing them polymer proposed show great potential programmable information encryption/anti‐counterfeiting.
