| 室温磷光因其长寿命发光特性,在信息加密、防伪标识和传感等领域展现出重要应用潜力。然而,纯有机体系中弱自旋-轨道耦合及显著的非辐射耗散过程使三重态激子的有效产生与稳定存在面临挑战。近年来,高分子基体通过构建受限微环境与调控分子间相互作用,为实现稳定有机室温磷光提供了重要材料平台。本文系统总结了高分子基体中有机室温磷光的光物理机制与结构设计策略。首先从三重态生成、非辐射衰减与氧淬灭等方面讨论室温磷光的基本光物理过程及其限制因素；随后重点归纳构建刚性环境、三重态产生增强、氧阻隔与三重态保护以及能量迁移与激子调控等高分子体系中的关键设计策略；在此基础上,总结高分子室温磷光材料在超长余辉信息加密、多色发射防伪以及刺激响应传感等方面的应用进展。最后,对高分子室温磷光材料在机制研究、结构调控及应用拓展等方面的发展方向进行展望。 |
| 英文摘要: |
| Room-temperature phosphorescence (RTP) has attracted considerable attention owing to its long-lived emission characteristics, which enable important applications in information encryption, anti-counterfeiting, and sensing. However, in purely organic systems, the weak spin–orbit coupling and significant non-radiative dissipation processes hinder the efficient generation and stable existence of triplet excitons. In recent years, polymer matrices have provided an important materials platform for achieving stable organic RTP by constructing confined microenvironments and regulating intermolecular interactions. This review systematically summarizes the photophysical mechanisms and structural design strategies of organic RTP in polymer matrices. First, the fundamental photophysical processes and limiting factors of RTP are discussed from the perspectives of triplet generation, non-radiative decay, and oxygen quenching. Subsequently, key design strategies in polymer systems are highlighted, including the construction of rigid environments, enhancement of triplet generation, oxygen blocking and triplet protection, as well as energy transfer and exciton regulation. On this basis, recent progress in the applications of polymer RTP materials is summarized, including ultralong afterglow information encryption, multicolor emission anti-counterfeiting, and stimulus-responsive sensing. Finally, future perspectives on mechanism studies, structural regulation, and application expansion of polymer RTP materials are discussed. |
