Electrophosphorescent materials can utilize both singlet and triplet excitons to emit light at the same time, which has high luminous efficiency and has drawn much attention from people. In this paper, the recent progress in the preparation of phosphorescent phosphorescent polymers by linking phosphorescent photoreceptor units to polymer chains through covalent bonding has been reviewed. The research progress of phosphorescent polymers with main chain, side chain and hyperbranched structure were summarized. The relationship between the luminescent properties and the molecular structure of these kinds of phosphorescent polymers was reviewed. Finally, based on the molecular structure design of electrophosphorescent luminescent polymer, some progress in the field of electrophosphorescent luminescent polymer has been made, and some problems existing in the field of electroluminescence have been analyzed. Phosphorescent polymer future direction of development.
