Crystalline metal-organic frameworks (MOFs) are formed by reticular synthesis, which creates strong bonds between inorganic and organic units. Careful selection of MOF constituents can yield crystals of ultrahigh porosity and high thermal and chemical stability. These characteristics allow the interior of MOFs to be chemically altered for use in gas separation, gas storage, and catalysis, among other applications. The precision commonly exercised in their chemical modification and the ability to expand their metrics without changing the underlying topology have not been achieved with other solids. MOFs whose chemical composition and shape of building units can be multiply varied within a particular structure already exist and may lead to materials that offer a synergistic combination of properties.
结晶金属-有机骨架（MOFs）是通过网状合成形成的，这种合成在无机和有机单元之间产生了很强的键。仔细选择 MOF 的组成部分可以得到超高孔隙率、高热稳定性和化学稳定性的晶体。这些特性允许对 MOFs 的内部进行化学修饰，用于气体分离、气体储存和催化等应用。与其他固体相比，MOFs 在其化学修饰方面通常具有更高的精度，并且能够在不改变基础拓扑结构的情况下扩展其度量。已经存在化学组成和构建单元形状可以在特定结构内多次变化的 MOFs，这可能会导致具有协同组合性能的材料。
