Organic solid-state materials with long-lived room-temperature phosphorescence (RTP) emission have been widely developed and applied in many fields, while works developing solution-phase were rarely reported owing to the ultrafast nonradiative relaxation quenchers from liquid medium. Herein, we report an ultralong RTP system water through assembly based on a β-cyclodextrin host p-biphenylboronic acid guest lifetime of 1.03 s under ambient conditions. It is worth noting that depends host-guest inclusion as well intermolecular hydrogen bonding interactions, which suppress avoid effectively. Furthermore, addition fluorescent dyes achieved tuning afterglow color radiative energy transfer reabsorption.

Abstract The development of bright and long‐lived aqueous room‐temperature phosphorescent (RTP) materials holds paramount importance in broadening the application scope RTP material system. However, conventional usually exhibit low efficiency short lifetime solution. Herein, an situ host–guest strategy is proposed to achieve cyanuric acid (CA)‐derived carbon nitrogen dots (CNDs) composite (CNDs@CA) that demonstrates a significant enhancement both quantum yield (QY) mediated by water. Detailed investigations reveal robust hydrogen bonding networks between CNDs@CA water effectively stabilize triplet excitons suppress nonradiative decays, as well facilitate efficient energy transfer from CA CNDs, thereby prolonging enhancing RTP. QY can be increased 26.89% (3.9‐fold increase) 951.25 ms (5.5‐fold increase), respectively, with incorporation 50 wt% under ambient conditions. Even fully environments (with up 400 added), exhibits persistent water‐boosted properties, demonstrating exceptional stability. property solutions presents potential for high signal‐to‐noise ratio afterglow bioimaging advanced information encryption.
