摘要：

A Cd(II)-MOF [Cd(L)(DMF)] (1) (H2L = 5-(4-pyridyl)-isophthalic acid) featuring high thermal and chemical stability has been solvothermally synthesized and characterized. Complex 1 is a robust multifunctional three-dimensional (3D) microporous framework possessing an unusual (4,5)-connected topological net. Activated 1 shows high-efficiency for the selective capture of CO2 over N-2 and CH4 under ambient conditions which ranks it among MOFs with the highest selectivity. In addition desolvated 1 exhibits good separation ratios of H-2 over N-2 at lower temperature as well as alcohols from water. In particular desolvated 1 demonstrates significantly higher adsorption enthalpies for CO2 and CH4 gas molecules which are in the range of the highest Qst values reported to date. Furthermore complex 1 displays visible photoluminescence in the solid state under UV irradiation.
