Molecules with permanent porosity in the solid state have been studied for decades. Porosity in these systems is governed by intrinsic pore space, as in cages or macrocycles, and extrinsic void space, created through loose, intermolecular solid-state packing. The development of permanently porous molecular materials, especially cages with organic or metal-organic composition, has seen increased interest over the past decade, and as such, incredibly high surface areas have been reported for these solids. Despite this, examples of these materials being explored for gas storage applications are relatively limited. This minireview outlines existing molecular systems that have been investigated for gas storage and highlights strategies that have been used to understand adsorption mechanisms in porous molecular materials.
固态下具有永久孔隙率的分子已被研究了数十年。这些体系中的孔隙率由内在孔隙空间（如笼状或大环结构中的孔隙）和外在空隙空间（通过松散的分子间固态堆积形成）共同决定。在过去十年中，永久性多孔分子材料，特别是有机或金属有机组成的笼状材料的开发受到了越来越多的关注，因此，这些固体材料的表面积已被报道达到了极高的水平。尽管如此，这些材料用于气体存储应用的实例相对有限。本综述概述了已被研究用于气体存储的现有分子体系，并强调了用于理解多孔分子材料吸附机制的策略。
