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1 H 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。

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 1 H NMR technique, electronic absorption and fluorescence spectroscopies in de-tails. The experimental results showed that cucurbit[7]uril can include C10DA forming a pseudorotaxane in-clusion 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.
