Recently, the development of porous absorbents for efficient CO 2 and I 2 capture has attracted considerable attention because of severe global climate change and environmental issues with the nuclear energy. Hence, a unique porous metal-organic framework (MOF), {[Co(L)]·DMF·2H 2 O} n ( 1 , DMF = N , N -dimethylformamide) with uncoordinated N atoms was rationally constructed via using a heterofunctional 4,6-bis(4'-carboxyphenyl)pyrimidine (H 2 L) linker. Interestingly, 1 exhibits exceptional properties for I 2 sorption, CO 2 capture, and catalytic conversion. Particularly, I 2 can be efficiently removed in both vapor and solution forms, and the adsorption amount can reach 676.25 and 345.28 mg g -1 , respectively. Furthermore, complex 1 displays high adsorption capacity for CO 2 (53.78 cm 3 g -1 , 273 K). Consequently, 1 is expected to be a promising and practical material for environmental purification due to its excellent adsorption properties.
