通过将光致发色团偶氮苯基团引入低分子量异二位AB型单体中，制备了光响应线性或交联超分子聚合物。紫外线照射后，线性和交联超分子聚合物的粘度均出现明显下降。更重要的是，由交联超分子聚合物形成的凝胶可以通过紫外或可见光照射实现可逆的光诱导溶胶凝胶转变。本文提出的工作提供了一种有效的策略，将光响应特性引入具有不同拓扑结构的超分子聚合物中，并制备复杂且高度有序的超分子结构。
By incorporating a photochromophore, an azobenzene group, into a low molecular weight heteroditopic AB-type monomer, photo-responsive linear or cross-linked supramolecular polymers were prepared. After UV irradiation, both the linear and cross-linked supramolecular polymers showed obvious decrease in viscosity. More importantly, gels formed from the cross-linked supramolecular polymer could realize reversible photo-induced sol gel transitions via UV or visible light irradiation. The work presented here provided an effective strategy to introduce photo-responsive properties into supramolecular polymers with different topological structures and to prepare complex and highly,ordered supramolecular structures.
