| 摘 要： | 利用紫外吸收光谱法、荧光光谱法和1H NMR技术等现代分析方法,测试了七元瓜环(cucurbit7]urils)与吖啶、9-氨基吖啶、3,6-二氨基吖啶(分别记为g1、g2、g3)的主客体作用。实验结果表明:在酸性或中性条件,用三种方法均能观察到七元瓜环与客体的相互作用,但在强碱性条件下,用上述方法观察不到主客体的相互作用,利用光谱法得到七元瓜环与g1、g2、g3均形成物质的量之比为1∶1的包合物,计算出相应的平衡常数,并利用核磁表征考察了主客体可能的作用模式。

| Abstract: | Interaction between cucurbit7]uril(Q7]) with the hydrochloride salts of acridine derivatives: acridine,9-amino-acridine,3,6-diamino-acridine(g1,g2,g3) in aqueous solution were investigated by using UV absorption spectroscopy,fluorescence spectroscopy and 1H NMR spectra.The experimental results revealed that three guests could form inclusion complexes with Q7] in acid and neutral solution,however,in alkaline conditions(pH > 12),we could not observe the interaction between three guests and Q7].Absorption ... |
