Heteroleptic metal-organic cages are prized for their structural complexity and multi-functionality. Controlling integrative self-sorting processes necessary to achieve defined self-assembly of these supramolecular hosts is a significant design challenge. In this work, ligand-tethering strategies are described that allow access to metal-organic cages with highly anisotropic cavities described by two inequivalent, unsymmetrical ligand scaffolds.

低对称金属有机笼中的伪异配性

杂配金属有机笼因其结构复杂性和多功能性而备受推崇。控制实现这些超分子主体的定义自组装所必需的综合自分类过程是一项重大的设计挑战。在这项工作中，描述了配体束缚策略，允许进入具有高度各向异性空腔的金属有机笼，这些空腔由两个不等价、不对称的配体支架描述。
