A 3D water-stable anionic metal–organic framework [Zn₄(hpdia)₂]·[NH₂(CH₃)₂]·3DMF·4H₂O (FJI-C4) was constructed based on an elaborate phosphorus-containing ligand 5,5′-(hydroxyphosphoryl)diisophthalic acid (H₅hpdia). FJI-C4 with narrow one-dimensional (1D) pore channels exhibits high selectivity of C₃H₈/CH₄ and C₂H₂/CH₄. It is the first time for the MOF which contains phosphorus for selective separation of methane from natural gas and pyrolysis gas.
