Abstract

Abstract : A microporous metal–organic framework based on rod SBUs with high water stability and good selectivity for CO2 separation has been successfully synthesized. Abstract : A novel water stable porous metal–organic framework (MOF), [Cu3 (OH)2 (IBA)2 (CH3 COO)2 ]·DMA (1 ) (HIBA = 4-(imidazol-1-yl)-benzoic acid, DMA = N, N -dimethylacetamide), has been solvothermally synthesized and structurally characterized. The framework of compound1 is constructed from rod SBUs with a new (5, 8)-connected topology. Compound1 exhibits exceptional chemical stability under various conditions (organic solvents, water, boiling water or pH = 1–8 acidic and basic aqueous solutions). Meanwhile, it exhibits good selectivity for CO2 over CH4 (6.6 for CO2 /CH4 = 0.5/0.5 and 5.8 for CO2 /CH4 = 0.05/0.95 under 1 bar at 298 K). The excellent stability of compound1 is of extreme importance for its practical industrial applications.
