Abstract

This paper reports on the supramolecular self-assembly of cyclopentano cucurbit[5]uril (CyP₅Q[5]), L-phenylalanine (L-Phe), and cadmium ions. The crystal structure is characterized using X-ray diffraction. The results show that the complex belongs to a monoclinic system with P2₁ space group. Cd²⁺ and L-Phe are coordinated in two CyP₅Q[5] portals via hydrogen bonds and ion-dipole interactions, respectively, so that the outer wall of the cucurbit[n]uril forms a porous channel. Each channel consists of six supramolecular chains, which may accommodate inorganic anions, such as CdCl\(_{4}^{{2 - }}\).

基于环戊烷葫芦[5] uril的三元超分子自组装模型

摘要

本文报道了环戊烷葫芦[5]尿素（CyP ₅ Q [5]），L-苯丙氨酸（L-Phe）和镉离子的超分子自组装。晶体结构使用X射线衍射表征。结果表明，该复合物属于具有P 2 ₁空间群的单斜系统。Cd ²⁺和L-Phe分别通过氢键和离子-偶极相互作用在两个CyP ₅ Q [5]门户中进行配位，因此葫芦丝[ n ] uril的外壁形成了一个多孔通道。每个通道由六个超分子链组成，它们可以容纳无机阴离子，例如CdCl \（_ {4} ^ {{2--}} \）。
