Recent Progress of Organic Room‐Temperature Phosphorescent Hydrogels

Organic room‐temperature phosphorescent (RTP) materials have garnered significant attention owing to their unique photophysical properties. Traditionally, the stabilization of triplet excitons in RTP materials necessitates a crystalline matrix or rigid polymer chain, which limits their use in flexible materials. In contrast, hydrogels offer biocompatibility, softness, and ease of processing. Therefore, incorporating phosphorescent molecules into hydrogel systems can expand the application potential of RTP materials. This concept summarizes recent advancements in RTP hydrogels, emphasizing their synthetic strategies and diverse applications.
