摘　　要：通过葫芦[6]脲(CB[6])与季铵化聚4-乙烯吡啶衍生物2在水溶液中于室温下进行超分子组装,得到一种新型的超分子聚合物3,并通过1HNMR,IR,元素分析,X射线粉末衍射分析(XRD)对其结构进行了表征,证实CB[6]位于2的侧基脂肪链上,通过非共价键与2结合;通过热重分析(TGA)、紫外-可见吸收(UV-vis)对其性质进行了研究,证实了超分子聚合物3比相应的聚合物2有更高的热稳定性,以及更强的UV-vis吸收.A new kind of supramolecular polymer 3 was prepared by supramolecular self-assembly of quaternized poly-4-vinylpyridine derivatives 2 with cucurbituril[6] (CB[6]) in water at room temperature. The chemical structure of 3 was confirmed by H-1 NMR, IR, elemental analysis and X-ray powder diffraction (XRD): CB[6] beads are localized round aliphatic chain of 2, and combine N+ by non-covalent bonds. The properties of 3 were researched by thermogravimetry analysis (TGA), UV-vis measurements. The results show that 3 has higher thermal stability and stronger absorption band than the parent polymers.
