Phosphorescent electroluminescent materials have attracted considerable attention due to their ability to efficiently utilize both singlet and triplet excitons and potentially high electroluminescent efficiency. In this paper, the recent progress of the synthesis of electrophosphorescent light-emitting polymers by covalently incorporating phosphorescent dyes into polymer molecular chain is summarized. The relationship of polymer structures and electroluminescent properties of copolymers is also reviewed, which mainly address the aspects by covalently introducing phosphorescent dyes into polymer main chain, or grafting phosphorescent dyes into polymer side chain, as well as fabricating hyperbranched electrophosphorescent light-emitting polymers with organometallic complexes as cores. Combined with the molecular design viewpoint and the achievement in the preparation of electrophosphorescent light-emitting polymers, the problems of the application of this kind of polymers in electroluminescent procedure are summarized, and our perspectives of the future development of this kind of polymers are also given.
