BioAIEgens derived from rosin: how does molecular motion affect their photophysical processes in solid state?
2021
Overview
The exploration of artificial luminogens with bright emission has been fully developed with the advancement of synthetic chemistry. However, many of them face problems like weakened emission in the aggregated state as well as poor renewability and sustainability. Therefore, the development of renewable and sustainable luminogens with anti-quenching function in the solid state, as well as to unveil the key factors that influence their luminescence behavior become highly significant. Herein, a new class of natural rosin-derived luminogens with aggregation-induced emission property (AIEgens) have been facilely obtained with good biocompatibility and targeted organelle imaging capability as well as photochromic behavior in the solid state. Mechanistic study indicates that the introduction of the alicyclic moiety helps suppress the excited-state molecular motion to enhance the solid-state emission. The current work fundamentally elucidates the role of alicyclic moiety in luminogen design and practically demonstrates a new source to large-scalely obtain biocompatible AIEgens.
To date we have a myriad of luminogenes at our deposal but many of them face problems like weakened emission in the aggregated state as well as poor sustainability. Here, the authors develop a class of rosin-derived luminogens with aggregation induced emission properties providing good biocompatibility and demonstrate their application in organelle imaging.
