Research on organic phosphorescence shows great promise, while classical small-molecule phosphorescence systems often face challenges in terms of cost, scalability, and functionalization. Polymer matrices provide powerful and versatile platforms for fabricating advanced functional organic phosphorescent materials. The unique microenvironment within dense polymer networks effectively stabilizes the generated triplet excitons, and the inherent diversity of polymers allows for broad functional integration. This perspective summarizes key construction strategies of polymer matrix-supported organic phosphorescent materials and highlights how these systems enable useful functions, including tunable luminescence, stimulus responsiveness, mechanical flexibility, water solubility, and potential biocompatibility, for targeted applications. Finally, we discuss critical challenges and future directions for further advancement of this rapidly growing field.
