Recently, polymer-metal-organic frameworks (polyMOFs) were reported as a new class of hybrid porous materials that combine advantages both organic polymers and crystalline MOFs. Herein, we report bridging coligand strategy to prepare types polyMOFs, demonstrating polyMOFs are compatible with additional MOF architectures besides the earlier IRMOF-1 type polyMOF. Gas sorption studies revealed these polyMOF exhibited relatively high CO2 but very low N2 sorption, making them promising for CO2/N2 separations. Moreover, demonstrated exceptional water stability attributed hydrophobicity polymer ligands well cross-linking chains within MOF.
