Recent Advances in Cyclodextrin‐Based Light‐Responsive Supramolecular Systems

Abstract Cyclodextrins (CDs), one of the host molecules in supramolecular chemistry, can host guest molecules to form inclusion complexes via non‐covalent and reversible host‐guest interactions. CD‐based light‐responsive supramolecular systems are typically constructed using CDs and guest molecules with light‐responsive moieties, including azobenzene, arylazopyrazole, o ‐nitrobenzyl ester, pyrenylmethyl ester, coumarin, and anthracene. To date, numerous efforts have been reported on the topic of CD‐based light‐responsive supramolecular systems, but these have not yet been highlighted in a separated review. This review summarizes the efforts reported over the past ten years. The main text of this review is divided into five sections (vesicles, micelles, gels, capturers, and nanovalves) according to the formation of self‐assemblies. This feature article aims to afford a comprehensive understanding of the light‐responsive moieties used in the construction of CD‐based light‐responsive supramolecular systems and to provide a helpful guide for the further design of CD‐based light‐responsive supramolecular systems.
