| Abstract: | A new kind of supramolecular polymer 3 was prepared by supramolecular self-assembly of qua-ternized poly-4-vinylpyridine derivatives 2 with cucurbituril6] (CB6]) in water at room temperature. The chemical structure of 3 was confirmed by 1H NMR, IR, elemental analysis and X-ray powder diffraction (XRD): CB6] 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. |
