Kinetically Controlled Porosity in a Robust Organic Cage Material

摘要

Microporous materials are of significant interest owing to their central role in gas storage, separation processes, and catalysis. Recently, microporous molecular solids composed of discrete, shape-persistent organic cages have received growing attention because they possess unique properties that set them apart from conventional, extended network materials, such as zeolites, metal-organic frameworks, and covalent organic frameworks. For example, molecular solids are readily solution-processable, provide facile access to multicomponent materials by mix-and-match synthesis, and, by virtue of their noncovalent intermolecular packing, can exhibit advanced properties, such as adsorbate-triggered on/off porosity switching.
