Title: A microporous metal–organic framework with butynelene functionality for selective gas sorption

A porous metal−organic framework ([Cu{sub 2}(BBTC)(H{sub 2}O){sub 2}]·2DMSO·4H{sub 2}O){sub n} (Cu-BBTC, BBTC=1, 1′-butadiynebenzene −3,3′,5,5′-tetracarboxylate; DMSO=dimethyl sulfoxide) was solvothermally synthesized from a tetracarboxylate ligand with butynelene functionality and structurally characterized. Cu-BBTC features a three-dimensional fof network with two types of cages, a small cage is about 14 Å in diameter and a large shows an ellipsoidal pore with about 14.2×22.6 Å in axes. The activated sample of Cu-BBTC, with Langmuir surface area of 1569 m{sup 2} g{sup −1}, exhibits selective gas adsorption behavior with respect to C{sub 2}H{sub 2}/CH{sub 4} and CO{sub 2}/CH{sub 4} at room temperature. - Graphical abstract: A microporous metal–organic framework with butynelene groups, ([Cu{sub 2}(BBTC)(H{sub 2}O){sub 2}]·2DMSO·4H{sub 2}O){sub n}, exhibits higher gas selective sorption towards C{sub 2}H{sub 2}/CH{sub 4} and CO{sub 2}/CH{sub 4} at room temperature with a selectivity of 5.7 and 4.1, respectively. Highlights: • Microporous dicopper MOFs containing butynelene functionality with fof structure. • Gas adsorption. • Selective separation of C{sub 2}H{sub 2}/CH{sub 4} and CO{sub 2}/CH{sub 4}.
