Metal–organic frameworks (MOFs) and porous coordination polymers (PCPs) have been well-recognized as emerging porous materials that afford highly tailorable and well-defined nanoporous structures with three-dimensional lattices. Because of their microporous nature, MOFs can accommodate small molecules in their lattice structure, thus discriminating them on the basis of their size and physical properties and enabling their separation even in the gas phase. Such characteristics of MOFs have attracted significant attention in recent years for diverse applications and have ignited a worldwide race toward their development in both academic and industrial fields. Most recently, new challenges in porous materials science demand processable liquid, melt, and amorphous forms of MOFs. This trend will provide a new fundamental class of microporous materials for further widespread applications in many fields. In particular, the application of flexible membranes for gas separation is expected as an efficient solution to tackle current energy-intensive issues. To date, amorphous MOFs have been prepared in a top-down approach by the introduction of disorder into the parent frameworks. However, this new paradigm is still in its infancy with respect to the rational design principles that need to be developed for any approach that may include bottom-up synthesis of porous soft materials.

通过金属有机笼的自组织进行多孔软材料的模块化设计

金属有机骨架（MOF）和多孔配位聚合物（PCP）已被公认为新兴的多孔材料，可提供高度可定制且定义明确的具有三维晶格的纳米多孔结构。由于其微孔性质，MOF可以在其晶格结构中容纳小分子，从而根据其大小和物理性质对其进行区分，即使在气相中也可以使其分离。近年来，MOF的这种特性在各种应用中引起了极大的关注，并引发了在其学术和工业领域发展的全球竞赛。最近，多孔材料科学的新挑战要求可加工的液态，熔融和非晶形式的MOF。这种趋势将为微孔材料提供一个新的基本类别，以在许多领域中进一步广泛应用。尤其是，将柔性膜用于气体分离的应用有望作为解决当前能源密集型问题的有效解决方案。迄今为止，无序MOF已经通过自上而下的方法通过将无序引入母体框架中来制备。但是，对于需要为可能包括自下而上合成多孔软材料的任何方法开发的合理设计原则而言，这种新范例仍处于起步阶段。通过自上而下的方法将无序引入母体框架中，可以制备出无定形的MOF。但是，对于需要为可能包括自下而上合成多孔软材料的任何方法开发的合理设计原则而言，这种新范例仍处于起步阶段。通过自上而下的方法将无序引入母体框架中，可以制备出无定形的MOF。但是，对于需要为可能包括自下而上合成多孔软材料的任何方法开发的合理设计原则而言，这种新范例仍处于起步阶段。
