Abstract

Abstract : An anionic multifunctional porous metal organic framework (MOF), [Cu2 THBA(H2 O)2 ]· (C3 H7 NO)12 · (H2 O)10 (1 ) (H4 THBA = p ‐terphenyl‐3, 2′′, 3′′, 5, 5′′, 5′′′‐ hexcarboxylic acid) with NbO‐type topology was synthesized and characterized. Due to multiple functional sites and suitable pore size, the desolvated compound1a exhibits high separation selectivity for C2 H2 /CO2 of 30 and C2 H2 /CH4 of 131 at 1 kPa at room temperature. Compound1 can also efficiently and completely separate methylene blue (MB + ) molecules of low concentrations from aqueous solution in 12 h. Abstract :
