Recently, polymer-metal-organic frameworks (polyMOFs) were reported as a new class of hybrid porous materials that combine advantages of both organic polymers and crystalline MOFs. Herein, we report a bridging coligand strategy to prepare new types of polyMOFs, demonstrating that polyMOFs are compatible with additional MOF architectures besides that of the earlier reported IRMOF-1 type polyMOF. Gas sorption studies revealed that these polyMOF materials exhibited relatively high CO2 sorption but very low N2 sorption, making them promising materials for CO2/N2 separations. Moreover, these polyMOFs demonstrated exceptional water stability attributed to the hydrophobicity of polymer ligands as well as the cross-linking of the polymer chains within the MOF.
最近，聚合物-金属-有机骨架（polyMOFs）被报道为一类新型的混合多孔材料，结合了有机聚合物和结晶 MOFs 的优点。在此，我们报告了一种桥连配体策略来制备新型的 polyMOFs，证明了除了早期报道的 IRMOF-1 型 polyMOF 之外，polyMOFs 还与其他 MOF 结构兼容。气体吸附研究表明，这些 polyMOF 材料表现出相对较高的 CO2 吸附，但对 N2 的吸附非常低，这使得它们成为 CO2/N2 分离的有前途的材料。此外，这些 polyMOFs 表现出优异的水稳定性，这归因于聚合物配体的疏水性以及聚合物链在 MOF 内的交联。
