Two fof-type porous metal–organic frameworks (MOFs), [Cu₂(bdfdpa)(H₂O)₂]·8DMF·2H₂O (JLU-Liu29) and [Cu₂(btadpa)(H₂O)₂]·7DMF·8H₂O (JLU-Liu30) (H₄bdfdpa = 5,5′-(benzo[1,2-b:4,5-b′]difuran-2,6-diyl)diisophthalic acid and H₄btadpa = 5,5′-(benzo[c][1,2,5]thiadiazole-4,7-diylbis(ethyne-2,1-diyl))diisophthalic acid), have been successfully synthesized by using different expanded tetracarboxylate ligands. Both of them exhibit good permanent porosity and high surface areas of 2205 and 1791 m² g^–1, respectively. Due to open metal sites, different functional groups, and suitable pore spaces, the two porous MOFs exhibit high adsorption performance for small molecule gases (CO₂, CH₄, C₂H₆, and C₃H₈) and removal of refractory organosulfur compounds.
