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1H NMR, 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 1H 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.

Key words: cucurbituril[6], quaternized poly-4-vinylpyridine derivative, self-assembly, supramolecular polymer
