<p>Stimuli-responsive chiral materials hold important potential for applications in smart photonic devices, chiral sensors, data storage, and other fields. Chiral supramolecular smart responsive materials based on azobenzene (Azo) self-assembly systems have attracted significant attention in recent years due to the dynamic and reversible chirality regulation under various external stimuli.

摘要

Stimuli-responsive chiral materials hold important potential for applications in smart photonic devices, chiral sensors, data storage, and other fields. Chiral supramolecular smart responsive materials based on azobenzene (Azo) self-assembly systems have attracted significant attention in recent years due to the dynamic and reversible chirality regulation under various external stimuli. This review systematically summarizes recent advances in the construction, regulation mechanisms, and functional applications of chiral supramolecular helical structures derived from Azo-based materials. Starting from molecular structure, assembly modes, and external stimuli responsiveness (such as light, heat, solvent, and pH), we discuss precise control over supramolecular chirality, including chiroptical switching, inversion, and asymmetric amplification. Furthermore, the potential applications of assembly materials containing Azo building units in chiroptical properties, chiral recognition, and nanoscopic/macroscopic chiral functional materials are highlighted. We hope this review will provide helpful insights for the design and fabrication of the new generation of smart chiral functional materials.
