Phosphorescent materials have attracted considerable attention due to their ability to efficiently utilize both singlet and triplet excitons. Polymer metal complex phosphorescent materials have the advantage of excellent light emission characteristics like small molecule metal complexes

and excellent physical properties like polymer materials

such as flexible

solution processable and good film-forming property. In this paper

the recent progress of polymer metal complex phosphorescent materials is summarized. The synthesis of polymer-metal complexes and their application in organic electroluminescent devices (OLED) are reviewed. Combined with the molecular design viewpoint and the achievement in the preparation of electrophosphorescent lightemitting 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.
