We report a hybrid solid system, UMOM-100-a and UMOM-100-b, synthesized by incorporation of Cu-based metal–organic polyhedra (MOPs) into a porous metal–organic framework (MOF) host, PCN-777. The MOP guests have acid (SO₃^–) functional groups, acting as functionalized nanocages, whereas the porosity is still maintained for proton conductivity. The key parameter for the UMOM-100 series is the number of MOPs inside a MOF, which controls the ratio between meso- and micropores, polarity, and finally proton conductivity. This is an example demonstrating a new design strategy for porous solids to add active components into porous MOFs, opening up possibilities in other applications such as solid-state electrolytes and heterogeneous catalysts.

MOP×MOF：金属有机多面体和金属有机质子传导性框架的协同组合

我们报告了一种混合固体系统UMOM-100- a和UMOM-100- b，它是通过将铜基金属有机多面体（MOP）掺入多孔金属有机框架（MOF）主体PCN-777中而合成的。该MOP客人有酸（SO ₃^-）的官能团，作为官能化纳米笼，而孔隙率仍然保持质子传导性。UMOM-100系列的关键参数是MOF内部的MOP数量，该数量控制中孔和微孔之间的比率，极性以及最终的质子传导率。这是一个示例，展示了一种用于多孔固体的新设计策略，可将活性成分添加到多孔MOF中，从而为固态电解质和非均相催化剂等其他应用打开了可能性。
