摘　　要：室温磷光材料由于其独特的三线态发光机理而具有Stokes位移大、激发态寿命长等特点。然而传统的室温磷光材料多含重金属原子,随之产生的生物毒性问题和环境污染问题限制了其应用。相比之下,纯有机室温磷光材料生产成本低、毒性小,可通过分子工程对有机结构进行灵活的设计和修饰,使其具有更丰富的发光特性,在防伪加密、有机电致发光、生物成像、传感检测等方面具有良好的应用前景。总结了近年来纯有机室温磷光材料在防伪与信息加密及储存、有机电致发光、生物成像、传感检测及其他应用方面的研究进展,并对纯有机室温磷光材料应用尚待解决的问题与未来可能的发展方向进行了简要总结和展望。Room-temperature phosphorescent materials have the characteristics of large Stokes shift and long excited-state lifetime due to their unique triplet state luminescence mechanism.However,the applications of traditional room temperature phosphorescent materials are limited by the biological toxicity and environmental pollution of heavy metal atoms contained.Pure organic room-temperature phosphorescent materials,with low production cost and low toxicity,show enhanced luminescence with abundant colors via molecular engineering of flexible structure design and modification and have good application prospects in anti-counterfeiting encryption,organic electroluminescence,biological imaging,sensing detection and other aspects.In this review,the recent research progress of pure organic room-temperature phosphorescent materials in anti-counterfeit as well as information encryption and save,organic electroluminescence,biological imaging and sensor detections were summarized.Finally,the existing problems and the possible development directions were discussed and prospected.
