So far,many strategies have succeeded in achieving efficient organic RTP materials by increasing the rate of intersystem crossing(ISC) and suppressing non-radiative transitions. In supramolecular chemistry, the control and regulation of molecular recognition based on the role of the host and vip in supramolecular polymers matrix, has attracted much attention. Recently, researchers have successfully achieved room temperature phosphorescence of pure organic complexes through host-vip interactions. The host molecule specifically includes the phosphorescent vip to reduce non-radiative transitions and enhance room temperature phosphorescence emission. This review aims to describe the developments and achievements of pure organic room temperature phosphorescence systems through the mechanism of host-vip interactions in recent years, and demonstrates the exploration and pursuit of phosphorescent materials of researchers in different fields.展开更多
