环戊基全取代六元瓜环与钾离子配合物的合成及其结构表征

Synthesis and Structure Characterization of the Fully Substituted Cyclopentano Cucurbit[6]uril with K^+ Complexes

金属与瓜环的配位化学是瓜环化学的主要研究内容之一。本文主要研究了环戊基全取代六元瓜环(Cy P6Q[6])与K+的配合物的合成,并利用X-射线单晶衍射法对其晶体结构进行了表征。结果表明:K+与Cy P6Q[6]的两个端口配位,形成了分子胶囊结构。相邻的瓜环通过与[Zn Cl4]2-的偶极作用,形成平面堆积结构,最后形成三维超分子自组装实体。

The coordination chemistry of metal and cucurbit[n]urils is one of the main research contents of cucurbit[n]urils chemistry. In this paper,Coordination of fully substituted cyclopentano cucurbit[6]uril（ CyP6 Q[6]） with K＋was studied,and its crystal structure was characterized by X-ray single crystal diffraction. The results show that： K＋coordinates with the two ports of CyP6Q[6] to form a molecular capsule structure. The adjacent cucurbit[6]uril forms a planar packing structure by dipolar interaction with [ZnCl4]^2-,and finally forms a three-dimensional supermolecular self-assembly entity.
