室温磷光性有机物由于三重态激子的参与和相对较慢的衰变速率，使其具有较长波长及长寿命的特性，让该类型化合物在光学器件、光催化反应、生物成像等领域中具有广泛的应用前景。目前构筑室温磷光有机体系主要是通过促进自旋轨道耦合和抑制三重态到基态的非辐射衰变来完成。对近年来室温磷光有机体系的发展进行归纳和总结，针对如何设计室温磷光有机体系提出了几种方法，并分析其原理，对未来室温磷光有机体系的发展与应用进行了展望。

In recent years, light?emitting organics have attracted widespread attention due to their unique functions. Among them, room temperature phosphorescent organics have the characteristics of longer wavelength and long life due to their triplet excitons and relatively slow decay rate, resulting in a wide range of application prospects in optical devices, photocatalytic reactions and other fields. At present, the construction of room temperature phosphorescent organic system is mainly accomplished by promoting spin?orbit coupling and suppressing the non?radiative decay process from the triplet state to the ground state. This article summarized the development of room temperature phosphorescent organic system in recent years. According to how to design room temperature phosphorescent organic system, several methods were proposed and their principles were analyzed, and the future development and application of room temperature phosphorescence organic system were prospected.
