摘　　要：Novel linear supramolecular polymers were successfully constructed by self-assemblies of coumarinbridged bifunctional UPy derivative.Benefitting from the photodimerization ability of the coumarin moieties,the linear supramolecular polymers could form the large three-dimensional polymer networks upon UV light irradiation via photo-cross-linking,which provides a viable and alternative procedure to modulate the properties of supramolecular polymers.Novel linear supramolecular polymers were successfully constructed by self-assemblies of coumarinbridged bifunctional UPy derivative.Benefitting from the photodimerization ability of the coumarin moieties,the linear supramolecular polymers could form the large three-dimensional polymer networks upon UV light irradiation via photo-cross-linking,which provides a viable and alternative procedure to modulate the properties of supramolecular polymers.
