Abstract
Cobalt-salen based porous ionic polymers which cobalt and halogen anions decorated on the framework effectively catalyze the CO2 cycloaddition reaction of epoxides to cyclic carbonates under ambient conditions. The cooperative effect of bifunctional active sites of cobalt as the Lewis acidic site and halogen anion as the nucleophile responds to the high catalytic performance. Moreover, density functional theory results indicate the cobalt valence state and corresponding coordination group influence the rate-determining step of CO2 cycloaddition reaction and the nucleophilicity of halogen anions.
