摘　　要：室温磷光不仅能直观地反映磷光发光体的激发态跃迁过程,而且在光电、传感、生物成像和信息加密等领域具有广阔的应用前景.因此,近年来室温磷光材料的研究引起了人们越来越多的兴趣与关注,成为发光材料、尤其是有机发光功能材料领域的一个新的研究热点.本综述总结了近年来关于有机小分子室温磷光材料的研究进展,主要围绕基于氢键的室温磷光材料、含有卤素的室温磷光材料、基于给体-受体(D-A)结构的室温磷光材料和具有圆偏振发光(CPL)性质的有机小分子室温磷光材料展开介绍.Room-temperature phosphorescence(RTP)can not only intuitively reflect the excited state transition process of the phosphorescent luminescence,but also has wide potential applications in optoelectronics,sensing,bioimaging and security devices.Consequently,more and more attention and interests on RTP materials have been attracted,which turned it to be one of hot topics in luminescence materials,especially,organic luminescence materials in recent years.The halogen bonds and hydrogen bonds between the molecules can fix the phosphor to suppress non-radiative transitions.A twisted donor-acceptor skeleton can promot efficient thermally activated delayed fluorescence(TADF)and also benefit to the RTP.Moreover,circularly polarized room-temperature phosphorescence(CP-RTP)also remains a daunting challenge to implant circularly polarized luminescence(CPL)in metal-free RTP materials.This review summarizes recent research progress on RTP of small organic molecules,mainly focusing on RTP materials based on hydrogen bonds,RTP materials containing halogens,RTP materials based on D-A structures and RTP materials with CPL properties.
