A CB[5] analogue based supramolecular polymer with AIE behaviors

Abstract

A supramolecular polymer has been successfully constructed by the self-assembly between a TPE derivative and a cucurbit[5]uril analogue—CyP₅TD[5], through portal interactions. Various characterization methods were adopted to prove the formation of the polymer, such as ¹H NMR, ITC, TEM and 2D DOSY ¹H NMR. In addition, supramolecular polymers exhibit a strong fluorescence in aqueous solution because of their aggregation-induced emission.
