摘　　要：合成并表征了六种不同碳链长度的1,ω-亚烷基二吡啶二溴化合物(客体),利用1HNMR技术、紫外吸收光谱和电化学方法考察了这些客体与六、七、八元瓜环(主体)相互作用,以及形成的主客体包结配合物的结构特征.研究结果表明,六种客体均能与六、七、八元瓜环形成主客体配合物,但作用模式随碳链的长度、瓜环的大小而各不相同.Six 1,ω-alkylenedipyridinium dibromide guests were synthesized and characterized, while structures and interaction of cucurbit[6,7,8]urils with the guests were investigated by ^1H NMR techniques in details, and the host-guest complex formation was also studied by UV-Vis and conductivity. The experimen- tal results showed that the host-guest complexes were formed between six guests and cucurbit[6,7,8]urils, while the interaction types were different for the six guests and cucurbit[6]uril, cucurbit[7]uril or cucurbit[8]uril respectively.
