摘　　要：In this study,we present a supramolecular templating approach for constructing polyimidazolium salt containing crown ether and cyclobutane moieties.This strategy involves the formation of metal-carbene templates,photochemical cycloaddition,and subsequent demetallation of metal ions.Driven by the host-guest chemistry between crown ether units and ammonium salts,we successfully fabricated a supramolecular polymer SPN1,which features imidazolium receptors and cyclobutane units.The obtained SPN1 demonstrates outstanding reversible stimulus-response,antibacterial behavior and conductivity.
