A two dimensional microporous metal-organic framework for selective gas separation

• A new tetracarboxylic acid was reported.
• A 2D metal-organic framework was synthesized and structurally characterized.
• The metal-organic framework exhibits high separation for CO2/N2 and CO2/CH4.

A new organic ligand of 1,1′-biphenyl-containing tetra-carboxylic acid (H4BPTT) and its first metal-organic framework [Zn2(BPTT)(H2O)2]n·(DMF)4.5n (1) was designed, synthesized and structurally characterized exhibiting two-dimensional distorted (4,4) topology. The activated 1a exhibits permanent porosity and moderately high selectivities for CO2/N2 and CO2/CH4 gas separations at room temperature.

A new two-dimensional microporous metal-organic framework has been synthesized from a novel organic linker and structurally characterized, exhibiting moderately high selectivities for CO2/N2 and CO2/CH4 gas separations at room temperature.Figure optionsDownload as PowerPoint slide
