Organic room temperature phosphorescence (RTP) materials with long afterglow phenomenon have unique advantages in anti-counterfeiting, biological diagnosis and treatment, optoelectronic devices and other fields. Intersystem crossing (ISC) of excitons and stable triplet excitons are the prerequisites for the organic materials to have phosphorescence emission. The guest-host doped strategy, as an emerging technology in recent years, has great advantages in the construction of organic RTP materials, which has attracted great attention and interest. The host matrix can not only help the energy transfer of the guest excitons, but the rigid structure of the host can effectively limit the motion of the guest molecules, thereby stabilizing the triplet excitons. In addition, the low content of the guest reduces the synthesis cost, the abundant varieties broaden the doped systems, and the special interaction of the hostguest can optimize and regulate the phosphorescence performance. However, despite the rapid development of doped system RTP materials, these systems are basically two-component systems, and facing the shortcomings of low performance and single function.
