摘    要:合成和表征了4个碳链长度不同二溴化1,n-亚烷基-二-2-甲基吡啶(客体,n=6,8,10,12),利用1H NMR技术、热重分析及紫外吸收光谱法考察了这些客体与七、八元瓜环(主体)的相互作用,以及形成的主客体包结物的结构特征.研究结果表明4个客体与七、八元瓜环形成不同的主客体包合物.七元瓜环可穿梭在线性客体分子上形成类轮烷型或哑铃型主客体包合物;而由于具有较大的空腔,八元瓜环可包容弯曲状的整个客体分子.

关 键 词:瓜环  二溴化1  n-亚烷基-二-2-甲基吡啶  类轮烷  超分子自组装

Abstract:Four 1,n-alkylene-di-2-methylpyridinium dibromide(n=6,8,10,12) guests were synthesized and characterized,and the host-guest interactions between cucurbit7 or 8]urils with these guests were also investigated by using 1H NMR tech-nique,thermogravimetry analysis and UV-Vis measurement in details.The experimental results revealed that it was different in the interaction models of the formed host-guest inclusion complexes between the cucurbit7]uril with the four guests and the cucurbit8]uril with the four guests.The cucurbit7]uril preferred to thread on the linear guests and formed pseudorotax-ane-like or "dumbbell"-like inclusion complexes,while the cucurbit8]uril preferred to included whole body of a guest in a fold manner due to having a larger cavity.
Keywords:cucurbit[7  8]uril  1  n-alkylene-bismethylpyridinium dibromide(n=6  8  10  12)  pseudorotaxane  supramolecular self-assembly
