摘要: Bio-based organic room-temperature phosphorescence (RTP) materials have drawn considerable interest due to their potential to replace conventional petroleum-based RTP materials and attain comprehensive full life-cycle carbon reduction, a feat attributable to their renewable, biocompatible, and environmentally friendly characteristics. Bio-based organic RTP materials derived from natural biomass (e.g., cellulose, lignin, chitosan) or biologically produced substances possess the capacity to spontaneously generate RTP or contribute to its generation. In this paper, the development lineage of bio-based RTP materials is introduced from the above two directions, including different systems, how to construct such systems, and the current progress. With strategies including hydrogen bonding networks, host-guest encapsulation, and polymeric matrices, it achieves RTP lifetimes up to seconds and full visible-band emission. It then explores the application scenarios that emerge from the natural advantages of these materials, including anti-counterfeiting and encryption, environmental monitoring, and bioimaging. Finally, it briefly discusses the potential challenges associated with bio-based RTP materials and envisions future development directions for them. While bio-based RTP materials rival petroleum-based counterparts in RTP efficiency, challenges persist: high production costs, poor environmental/thermal stability, and balancing degradability with durability. These sustainable alternatives offer biodegradability, renewability, and reduced lifecycle carbon emissions, utilizing agricultural byproducts (e.g., corn stalks, shrimp shells) to enhance circular economies.
