五元瓜环与钕离子在四氯酸锌离子诱导下构筑的配合超分子自组装（英文）

Coordination and Supramolecular Assemblies of Neodymium Cation with Cucurbit[5]uril

在四氯酸锌离子诱导下,五元瓜环能与钕离子构筑形成二维配合超分子自组装。在HCl介质中,Zn2+容易形成四氯酸锌离子,在其诱导作用下,钕离子和五元瓜环端口羰基氧直接配位形成二维超分子自组装体。结果表明锌离子作为一种结构导向剂在形成瓜环基超分子自组装体中起到重要作用。

In the presence of tetrachlorozincate [ZnCl4]2- anion, three complexes of the coordination of neodymium （Nd3＋） cations with cucurbit[5]uril （Q[5]） and corresponding supramolecular assemblies were described. The [ZnCl4]2- anions gave rise to a ＂honeycomb effect＂ that resulted in the formation of Nd3＋/Q[5]-based linear coordination polymers and two dimensional networks. Examination revealed that the Zn2＋ cations can not only coordinate to Q[5], but also form [ZnCl4]2- anions which lead to the formation of a Zn2＋/Q[5] complex-based honeycomb framework in which the channels are filled with [ZnCl4]2- anions.
