| 摘 要： | 分别用核磁共振、紫外可见吸收和X射线单晶衍射方法研究对称四甲基六元瓜环与2-氨基甲基吡啶的相互作用及其结构特征. 1H NMR谱图和紫外可见吸收光谱图清晰表明, 2-氨基甲基吡啶与对称四甲基六元瓜环有明显的相互作用, 客体2-氨基甲基吡啶的吡啶环部分进入了瓜环空腔, 1H NMR谱图相关质子峰的积分强度以及客体吸光度随主体瓜环浓度变化明确表示它们之间形成了1∶1的包结配合物, 此包结比并不随瓜环的浓度增加而改变. X射线单晶衍射法对包结配合物晶体的测定进一步证实了核磁共振、紫外可见吸收方法所得结论.

| Abstract: | Interaction and structure of a host-guest inclusion complex of symmetrical tetramethyl substituted cucurbit6]uril (TMeQ6]) with 2-(aminomethyl)pyridine (amp) have been studied by using 1H NMR technique, UV-visible spectrophotometry and single crystal X-ray diffraction determination. The experimental results from 1H NMR and UV-visible spectra revealed that the amp as a guest enters into the cavity of TMeQ6] to form a host-guest inclusion complex of TMeQ6] and amp with a constant ratio of 1∶1. The single crystal X-ray diffraction determination further confirmed the conclusions. |
