supramolecular polymer with a high degree of polymerization and viscosity has been constructed based on the strong host–guest interaction between p‐sulfonatocalix[4]arenes (SC4As) and viologen. A homoditopic doubly ethyl‐bridged bis(p‐sulfonatocalix[4]arene) (d‐SC4A) was prepared and its binding behavior towards methyl viologen compared with the singly ethyl‐bridged bis(p‐sulfonatocalix[4]arene) (s‐SC4A)
具有高聚合度和粘度的水溶性超分子聚合物已经构建了基于之间的强主-客体相互作用p -sulfonatocalix [4]芳烃(SC4As)和紫精。甲homoditopic双乙基桥连双(p -sulfonatocalix [4]芳烃)(d -SC4A)溶液并朝甲基紫精及其结合行为与单乙基桥连的双相比(p -sulfonatocalix [4]芳烃)(小号- SC4A)通过NMR光谱和等温滴定热法测定。通过使用紫精二聚体(bisMV 4+)作为同位异位客体,两种线性AA / BB型超分子聚合物d ‐SC4A⊃bisMV 4+和s‐SC4A⊃bisMV 4+已成功构建。与s- SC4A⊃bisMV4 +相比,d- SC4A⊃bisMV4 +显示出更高的溶解度和粘度,并且具有粘度,扩散有序NMR光谱,动态光散射和原子力显微镜测量的特点。此外,由于紫精是电活性的,因此聚合物对电刺激具有响应性,这已通过
