近年来葫芦脲因为其在超分子化学领域有着巨大的潜在应用价值而备受研究者关注。本文描述了一种两臂均为葫芦脲潜在包结点的V型菁染料分子DP与葫芦脲[8]之间的包结现象,通过一维、二维核磁共振氢谱、质谱和紫外可见吸收光谱等手段对包结物进行了研究,结果表明DP与葫芦脲[8]形成1∶1包结物,且其两臂均被葫芦脲[8]所环绕,相关包结常数为(5.4±0.4)×105。 In recent years, cucurbiturin has drawn much attention of researchers because of its huge potential value in the field of supramolecular chemistry. In this paper, an entrapment phenomenon between V-cyanine dye molecule DP and cucurbituril [8], which is a potential inclusion site of both cucurbiturils, is described. One-dimensional and two-dimensional nuclear magnetic resonance Absorption spectra and other means were used to study the inclusion complex. The results show that DP and cucurbit [8] form a 1: 1 inclusion complex, and both arms are surrounded by cucurbituril [8]. The relative entanglement constant is (5.4 ± 0.4) × 105.
