Abstract
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. [Display omitted]
