Stimuli-Responsive Supramolecular Assemblies between Twisted Cucurbit[14]uril and Hemicyanine Dyes and Their Analysis Application.

Two supramolecular assemblies between twisted cucurbit[14]uril and hemicyanine dyes have been successfully constructed on the basis of host-guest recognition. These supramolecular assemblies could be reversibly switched under acidic and neutral conditions. Furthermore, they responded to selected chemical stimuli such as methyl violet, thereby exhibiting potential analysis application.
