摘要:

设计合成了具有多个作用位点的长链分子N,N'-二甲基-苯甲基-1,10二氨基癸烷(C10DA)并将其作为客体, 利用1H NMR、 紫外吸收光谱及荧光光谱等手段考察了C10DA与七元瓜环(主体)的相互作用, 以及形成的主客体包结配合物的结构特征. 结果表明, 随着主客体摩尔比的变化, 其作用模式从类轮烷型包结配合物转变成哑铃型包结配合物, 这一特性在分子器件的制备方面具有潜在的应用前景.

关键词: 瓜环, 类轮烷, 哑铃型包结配合物, 超分子自组装

Abstract:

Molecular motions are quite common in biosystems and closely related to macroscopic motions guest. In the present work, N,N'-bis(4-dimethylaminobenzyl)-decane-1,10-diamine(C10DA) with multiple binding sites was designed and synthesized, while the structures and interaction of cucurbit[7]uril with the guest were investigated by 1H NMR technique, electronic absorption and fluorescence spectroscopies in details. The experimental results showed that cucurbit[7]uril can include C10DA forming a pseudorotaxane inclusion complexes or dumbbell-shaped inclusion complexes by changing the molar ratio of the host and guest. This observation contributes to a deeper understanding in molecular recognition, design and construction of novel molecular machines.

Key words: Cucurbit[n]uril, Pseudorotaxane, Dumbbell inclusion complex, Supramolecular self-assembly
