Abstract The development of stimuli‐responsive and color‐tunable chiral organic afterglow materials has attracted great attention but remains a daunting challenge. Here, simple yet effective strategy through the construction dynamic H‐bonding network is proposed to explore multi‐color by doping self‐designed phosphorescent chromophore into polyvinyl alcohol matrix. A deep blue system with lifetime up 3.35 s, quantum yield 25.0%, luminescent dissymmetry factor 0.05 achieved reversible formation breakdown upon thermal‐heating water‐fumigating. Moreover, can be obtained energy transfer, allowing establishment information displays high‐level 4D encryption. This work not only offers facile platform develop advanced also opens new avenue for developing next‐generation optical technology enhanced functionality responsiveness.

Host/guest doping is an effective approach to achieving room-temperature phosphorescence (RTP). However, the influence of host matrix on systems still unclear, and it difficult select suitable species for a certain guest emitter. This study prepared series host/guest RTP materials with dynamically adjustable time color by non-RTP material in various that were easy crystallize. The varying afterglow originated from difference Förster energy transfer between guest. Specifically, change yellow green was realized host’s molecular structure. further revealed importance proper levels, ability generate long-aging triplet excitons, Additionally, multiple information encryption anti-counterfeiting developed leveraging different colors durations, reflecting unique performance advantages long-afterglow applications.

Abstract Organic circularly polarized luminescence (CPL) plays crucial roles in chemistry and biology for the potential chiral recognition, asymmetric catalysis, 3D displays, biological probes. The long‐lived luminescence, large Stokes shift, unique chiroptical properties make organic room‐temperature phosphorescence (CPP) a new research hotspot recent years. Nevertheless, achieving high‐performance CPP is still challenging due to sensitivity complexity of integrating triplet excitons polarization within materials. This review summarizes latest advances CPP, ranging from design strategies photophysical underlying mechanisms applications. Specifically, generating are systemically categorized discussed according interactions between units chromophores. applications light‐emitting diodes, sensing, afterglow information encryption also illustrated. In addition, we present current challenges perspectives on developing CPP. We expect this provide some instructive principles fabricate materials, offering an in‐depth understanding mechanism paving way toward diverse practical
