Research Progress on Aggregation Science-Enabled Luminescent Materials from Forest Biomass

Abstract

Most traditional natural products exhibit weak or no luminescence owing to the lack of large conjugated systems. Moreover, the strategy of introducing luminescent chromophores to modify these natural products is often hampered by aggregation-induced quenching (AIQ) effects. In recent years, aggregate science-based research on forestry biomass-derived luminescent materials has successfully addressed this technical bottleneck, thus establishing forestry biomass as a vital reservoir for luminescent material development. From the perspective of aggregate science, this paper outlines two luminescence mechanisms centered on restricted molecular motion. It systematically summarizes the latest research progress in luminescent materials derived from forestry biomass and practical application attempts in intelligent anti-counterfeiting, bioimaging, food detection, and other fields, classified into three categories: natural small molecules, derivatives of natural small molecules, and natural polymers and their derivatives. Finally, future research directions are proposed, offering novel research insights and development directions for the innovative utilization of forestry biomass.
