摘　　要：设计、合成了具有多作用位点的长链分子N,N'-二甲基-苯甲基-1,10二氨基癸烷(N10)作为客体,利用1H NMR技术、紫外吸收光谱法以及荧光光谱法等手段考察了N10与八元瓜环(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。研究结果表明其作用模式为类轮烷型包结配合物和哑铃型包结配合物相互共存,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 （N10） with multiple binding sites was designed and synthesized, while structures and interaction of cucurbit [ 8 ] uril with the guest were investiga- ted by 1H NMR techniques, electronic absorption and fluorescence spectroscopic in details. The experimental re- suits showed that cucurbit[ 7 ] uril can include N10 forming a pseudorotaxane inclusion complexes or dumbbell- shaped inclusion complexes. This observation contributes to a sign and construction of novel molecular machines. deeper understanding in molecular recognition, de-
