Synthesis and characterization of polymerizable MOFs for the preparation of MOF/polymer mixed matrix membranes

Mixed-matrix membranes (MMMs) comprising polymer matrices and metal-organic frameworks (MOFs) provide efficient and economic CO₂ separation. One major challenge is to construct continuous and defect-free MMMs due to poor MOF/polymer compatibility. Here, this protocol describes the step-by-step details for synthesis of desired linkers that allow the fabrication of new polymerizable MOFs containing vinyl groups (BUCT MOFs) and the preparation procedures of defect-free MMMs with enhanced MOF/polymer interfacial adhesion and boosted gas separation performances. For complete details on the use and execution of this profile, please refer to Chen et al. (2021).
