利用HPLC法考察了六、七元瓜环(Q[6], Q[7])与邻苯二胺(g1)、间苯二胺(g2)、对苯二胺(g3)、邻硝基苯胺(g4)、间硝基苯胺(g5)、对硝基苯胺(g6)的相互作用. 实验结果表明: Q[6]可与客体g1～g3, g5形成1∶1的包结配合物; Q[7]与客体g1～g6形成1∶1包结配合物, 同时计算了包结配合物的包结稳定常数, 探讨了主-客体的相互作用模式, 并利用1H NMR、紫外吸收光谱法进行了佐证.

关键词: HPLC, 紫外吸收光谱, 1H NMR, 瓜环, 包结稳定常数

Interaction of cucurbit(n)uril (n＝6,7) with aniline and its derivatives was studied by using high performance liquid chromatography (HPLC). The guests are o-phenylenediamine (g1), m-phenylenediamine (g2), p-phenylenediamine (g3), o-nitroaniline (g4), m-nitroaniline (g5) and p-nitroaniline (g6). The experimental results revealed that Q[6] bound only g1～g3 and g5 respectively to form the inclusion complex in a rario of 1∶1; while Q[7] was observed to form a 1∶1 host-guest product with guests g1～g6 respectively. The stability constants and ratio of host∶guest were determined. And the interaction model of the inclusion complexes was proposed, which were further confirmed by UV absorption spectroscopy and 1H NMR technique.

Key words: HPLC, UV absorption spectroscopy, 1H NMR, cucurbit(n)uril, stability constant
