Enhancing Strategies for the Assembly of Metal–Organic Systems with Inherent Cavity-Containing Calix[4]arenes

p-Carboxylatocalix­[4]­arenes have recently emerged as useful building blocks in the assembly of both discrete and polymeric coordination compounds. Steric effects of coligands used are now shown to dramatically influence the assembly process, dictating the assembly of one-dimensional (1D)-three-dimensional (3D) systems. Solvothermal techniques have also been found to promote formation of 3D systems with a sterically undemanding coligand.对羧基杯[4]芳烃（p-Carboxylatocalix[4]arenes）近年来已成为构建离散型与聚合型配位化合物的关键构筑基元。现已表明，所采用的共配体的空间位阻效应可显著调控组装过程，支配其形成一维（1D）至三维（3D）的各类结构体系。此外，溶剂热技术已被证实可促进空间位阻较小的共配体体系生成三维结构。
