摘　　要：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1HNMR，质谱和^1H ROESYNMR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.
