Supramolecular assembly with stimuli-responsive circularly polarized luminescence

In recent years, circularly polarized luminescent (CPL) materials have attracted much interest because of their promising applications in many research fields, such as photoelectric devices and information storage systems. This importance has stimulated the rapid development of stimuli-responsive CPL-active materials. Responsive chiral multicomponent assembled materials are prepared by incorporating chiral group and responsive luminescent components, which play an important role in developing the intelligent CPL materials. Depending on the non-covalent interactions during the process of multicomponent co-assembly, the supramolecular assembly systems provide various methods to regulate CPL features using external stimuli such as temperature, light, solvent, pH, metal ions, electric fields, and mechanical force. This review summarizes the recent progress in stimuli-responsive multicomponent co-assembled systems major when gel and chiral nematic liquid crystal are present. Future challenges and opportunities are also briefly highlighted.
