Abstract

A novel pillar-layer porous lanthanide metal-organic framework [Tb₃(ODA)₃(BPDC)₃Na₂]_n·G_x (UTSA-222, G = guest molecules) was constructed from an organic ligand [1,1'-biphenyl]-4,4'-dicarboxylate (BPDC^2-) and a lanthanide metalloligand [Tb(ODA)]⁺ (H₂ODA = oxydiacetic acid). The UTSA-222 contains two-dimensional intersecting channels with the Brunauer-Emmett-Teller surface area and pore volume of 703 m² g^-1 and 0.344 cm³ g^-1, respectively, for the activated sample. It shows moderately high adsorption selectivity for C₂H₂/CO₂ and C₂H₂/CH₄ separations at 1 atm and room temperature.
