Abstract
Two carboxyl‐functional Mn (III)–porphyrins reacted with two metal nitrates (Cr (NO3)3·9H2O and Al (NO3)3·9H2O) via solvothermal method, respectively, to produce four metalloporphyrin‐based metal organic gels (MOGs). To remove unreacted metal salts and DMF, the gels were dealt with Soxhlet extraction and supercritical CO2. Finally, four desired porous coordination polymers (PCPs) were prepared. The newly synthesized PCPs were characterized by FT‐IR, UV–vis, SEM, and TEM. The contrast experiments show these PCPs possess good catalytic activities for the cycloaddition reactions of epoxide and CO2 under mild and solvent‐free conditions using tetrabutylammonium bromide (TBAB) as co‐catalyst.
