大多数具有分子尺度孔的纳米多孔材料是由定向共价键或配位键组成的，如多孔金属-有机骨架和有机网络聚合物。相比之下，由离散的有机分子组成的纳米多孔材料很少遇到，这些分子之间只有微弱的非共价相互作用。事实上，大多数有机分子在固体状态下有效地堆积，使空隙体积最小化，从而导致无孔材料。近年来，人们发现了大量的纳米多孔有机分子材料(晶态或非晶态)，并通过气体吸附证实了其孔隙度。所有这些材料都是在这一亮点中汇编的。此外，还讨论了多孔有机分子材料相对于多孔网络材料的优点。
Most nanoporous materials with molecular-scale pores are composed of directional covalent or coordination bonds, such as porous metal-organic frameworks and organic network polymers. By contrast, nanoporous materials comprised of discrete organic molecules, between which there are only weak non-covalent interactions, are seldom encountered. Indeed, the majority of organic molecules pack efficiently in the solid state to minimize the void volume, leading to nonporous materials. In recent years, a large number of nanoporous organic molecular materials (crystalline or amorphous) were discovered and their porosity was confirmed by gas adsorption. All of these materials were compiled in this highlight. In addition, advantages of porous organic molecular materials over porous networks are discussed.
