•A porous 2D metal–organic framework is synthesized under solvothermal condition.•The dicarboxylate ligand is asymmetric and prolonged by alkyne groups.•The activated compound exhibits selective adsorption of CO2 over N2.
A new porous 2D metal–organic framework [Cu(L)DMF]·2H2O (1) has been synthesized by self-assembling copper paddle-wheel units with an asymmetrical dicarboxylate ligand prolonged by alkyne groups, 3,3′-(ethyne-1,2-diyl)dibenzoic acid (H2L) under solvothermal condition. The activated sample 1a displays selective adsorption of CO2 over N2 and shows low isosteric heat (Qst) of CO2 adsorption.
