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.1HNMR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,1HNMR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. The interaction and structural characterization of symmetrical tetramethylcarbamates with 2-aminomethylpyridine were investigated by 1H NMR and UV-Vis absorption and X-ray single crystal diffraction, respectively. The 1 H NMR spectrum and UV-Vis absorption spectra clearly show , 2-aminomethylpyridine and tetramethyl tetraguanocyclozasin ring there is a clear interaction, the object 2-aminomethyl pyridine pyridine ring part into the melon ring cavity, 1HNMR spectra associated proton peak intensity and The change of guest absorbance with the change of cucurbitacin concentration clearly indicates that a 1: 1 inclusion complex is formed between them, and the inclusion ratio does not change with the concentration of cucurbit [2]. X-ray single crystal diffraction The determination further confirmed the NMR, UV-visible absorption of the conclusions obtained.
