摘要
在盐酸介质中,通过四氯合锌离子诱导,碱金属离子能与反式六元瓜环端口羰基氧原子直接配位构筑形成超分子自组装体。单晶结构表明在HCl介质中,四氯合锌离子形成"蜂巢结构",而且在[ZnCl_4]^(2-)诱导作用下,碱金属离子和反式六元瓜环端口羰基氧直接配位形成一维超分子自组装体而填充在"蜂巢结构"中。
Coordination in supramolecular assemblies formed in aqueous HCl solution was investigated by reacting alkali cations (M+) and inverted cucurbit[6]uril (iQ[6]) in the presence of the structure-directing agent tetrachloride zincate anion ([ZnCl4]2-). Single-crystal X-ray diffraction analysis revealed that the iQ[6]-M+-[ZnCk4]2-- HCl interaction systems yielded a supramolecular assembly consisting of iQ[6]/M+-based linear coordination polymers residing within the pores of a honeycomb-like framework of [ZnCl4]2- anions. Close inspection revealed that different iQ[6]/M+/[ZnCl4]2--based supramolecular assemblies (M=Na, K, Rb) presented different porous conformations and displayed different absorption properties.
