摘要 在[ZnC l4]2-阴离子存在的条件下,制备了六元瓜环(Q[6])与1,6-二吡啶己烷(Hdpy)形成包结配合物的晶体,该晶体是由主客体通过Q[6]空腔的疏水作用以及外部的离子-偶极作用形成的稳定的类轮烷结构,相邻类轮烷之间通过[ZnC l4]2-阴离子与水分子以及瓜环端口羰基氧原子氢键作用连接成超分子链。 A single crystal based on cucurbit [ 6 ] uril ( Q [ 6 ] ) with 1,6-Hexamethylenedipyridine was synthesized, and it was structurally characterized by single-crystal X-ray diffractions determination. The crystal structure of the compound shows that a stable pseudorotaxane inclusion complex is formed by combining the hydropho- bic cavity and the outer portal dipole ion interactions, and the pseudorotaxane assembled through hydrogen bonding to form supramolecular chain.
