摘要
A new coordination polymer, formulated as {[Co-2(mu(8)-abtc)(betib)DMF}(n) (1) (abtc, 3,3',5,5'-azobenzenetetracarboxylate; betib, 1,4-bis(2-ethylimidazol-1-yl)butane), was synthesized with 3,3',5,5'-azobenzenetetracarboxylic acid and flexible betib ligand. Complex 1 was immersed in methanol to obtain {[Co-2(mu(8)-abtc)(betib)]center dot H2O}(n), (2). The complexes were characterized by IR spectra, elemental analyses, single-crystal and powder X-ray diffractions, and thermal analyses. X-ray results demonstrated that complexes 1 and 2 had a porous 3D framework with sqc5381 net. Complex 2 was activated at 105 degrees C (2a), and CO2 and iodine adsorption properties of 2a were studied. The CO2 uptake capacity of 2a was 52.94 cm(3)/g10.40%). Moreover, complex 2a encapsulated 30.34 and 21.98% iodine in the vapor phase and solution, respectively, which corresponded to 1.975 and 1.42 molecules of iodine per formula unit, respectively.
