Recent Progress in Circularly Polarized Luminescent Materials Based on Cyclodextrins.

Circularly polarized luminescence (CPL) materials have been widely used in the fields of bioimaging, optoelectronic devices, and optical communications. The supramolecular interaction, involving harnessing non-covalent interactions between host and guest molecules to control their arrangements and assemblies, represents an advanced approach for facilitating the development of CPL materials and finely constructing and tuning the desired CPL properties. Cyclodextrins () are cyclic natural polysaccharides, which have also been ubiquitous in various fields such as molecular recognition, drug encapsulation, and catalyst separation. By adjusting the interactions between and guest molecules precisely, composite materials with CPL properties can be facilely generated. This review aims to outline the design strategies and performance of -based CPL materials comprehensively and provides a detailed illustration of the interactions between host and guest molecules.
