Polymer-based Organic Room-temperature Phosphorescent Materials

Room-temperature phosphorescent (RTP) materials have garnered significant attention in recent years owing to their diverse applications in optoelectronics and bioelectronics, particularly metal-free RTP polymers. The RTP polymers possess inherent benefits such as excellent flexibility, high thermal stability, easy processing and low cost in large-scale production and applications. Besides, complex polymer networks and multi-level microphase structures may provide a rigid environment for the generation of RTP, along with dynamic photophysical properties by controlling the morphology and microphase structures. This chapter outlines the recent advancements in metal-free RTP polymers, encompassing synthetic strategies via chemical bonding engineering and nonvalent bonding, photophysical properties, luminescent mechanisms and potential applications. Finally, the advancements and challenges faced in the development of metal-free RTP polymers have been comprehensively discussed, providing an outlook for future research directions in this field.
