Two carboxyl‐functional Mn (III)–porphyrins reacted with two metal nitrates (Cr (NO 3 ) 3 ·9H 2 O and Al (NO 3 ) 3 ·9H 2 O) 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 CO 2 . 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 CO 2 under mild and solvent‐free conditions using tetrabutylammonium bromide (TBAB) as co‐catalyst.
