Organic dyes are common toxic pollutants that pose a serious threat to humans and aquatic life. Metal-organic framework (MOF) and Metal-organic cage (MOC), combined with polymers can leverage their inherent pore structures to create membranes with high permeability and selectivity for effective dye removal. This paper reports the use of MOF as the aqueous phase monomer for interfacial polymerization with the organic phase monomer (trimesoyl chloride, TMC). Subsequently, a secondary interfacial polymerization using MOC was performed to fix the voids between MOF and TMC. The resulting membrane exhibits a dense structure and a high loading of porous material. The composite membrane possesses a unique pore structure, including the network pores formed during interfacial polymerization and the intrinsic micropores of the crystalline porous material, which provides the membrane with high water permeability and excellent sieving performance. Experimental results show that the composite membrane has a water permeance of 18 Lm-2h-1bar-1 and a dye removal rate of 99.9%, demonstrating that composite membranes constructed using crystalline porous materials as the aqueous phase monomer are highly effective in removing soluble pollutants from aqueous solutions.
