Metal–organic framework (MOF) materials, which are constructed from metal ions or metal ion clusters and bridging organic linkers, exhibit regular crystalline lattices with relatively well-defined pore structures and interesting properties. As emerging inorganic and organic hybrid materials, MOF materials are very appealing to be assembled into MOF membranes for separation and catalysis applications because their pores can be rationally controlled by the interplay of both inorganic metal ions and organic linkers, and their pore surfaces can be readily functionalised through a variety of approaches.^[1,2] The ability to rationally tune the structure of the materials may create unique interactions with guest molecules and thus achieve unusual chemicophysical properties in adsorption and separation.
