通过葫芦[6]脲(CB[6])与两个质子化的1,4-丁二胺在水溶液中于室温下进行超分子自组装, 得到一种新型的准轮烷. 通过1H NMR, 质谱和1H ROESY NMR对其结构进行了表征, 证实CB[6]位于质子化1,4-丁二胺的脂肪链上, 通过非共价键与1,4-丁二胺结合, 并且主体(CB[6])与客体的结合的物质的量之比为2∶1.

The synthesis of a novel pseudorotaxane formed by cucurbit[6]uril (CB[6]) as the macrocycle and two diprotonated diaminobutane moieties as the “string” was reported. The compounds have been characterized by 1H NMR spectroscopy, mass spectrometry and 1H ROESY NMR spectroscopy. Two CB[6] beads were localized on aliphatic chain to combine N＋ of two diprotonated diaminobutane moieties by non-covalent bonds, and the molar ratio of CB[6] to the “string” was 2∶1.

Key words: supramolecule, self-assembling, pseudorotaxane, cucurbit[6]uril
