p-Carboxylatocalix[n]arenes have emerged as useful building blocks for the construction of a diverse range of supramolecular assemblies. A convenient route to a p-carboxylatocalix[4]arene that is locked in a partial-cone conformation is presented. The conformation
gives the molecule markedly different topological directionality relative to those previously used in self- and metal-directed assembly studies.
p-羧基卡利克斯[n]芳烃已经成为构建各种超分子组装的有用基础模块。提出了一种方便的途径,用于制备锁定在部分锥形构象中的p-羧基卡利克斯[4]芳烃。该构象使该分子在自组装和金属引导组装研究中相对于以前使用的分子具有显著不同的拓扑定向性。
