瓜环与长链有机二元胺形成自组装类轮烷的研究

Study on Pseudorotaxane of Cucurbit[n=5-8] uril with Alkylane-diamines

本文以核磁共振谱仪为手段 ,对一类新发现的环状化合物—瓜环 (cucurbit[n]uril,n =5- 8)为主体 ,链状有机胺为轴材的自组装类轮烷的形成过程进行了初步的研究。没有迹象表明在实验条件下五元瓜环能与长链二胺形成类轮烷结构 ;六、七元瓜环很容易与长链二胺自组装形成类轮烷结构 ;

In this paper, we report self assembly pseudorotaxane of cucurbit\uril with alkylane diamines by suing 1H NMR spectra (n=5-8). The experiment results reveal that the cucurbit\uril can not form pseudorotaxane with alkylane diamines under the experimental condition, while the cucurbit\uril can easily assemble to form pseudorotaxanes with alkylane diamines, and the diamines can intry or leave the cavity of cucurbituril without obvious hindrance.
