A novel kind of functional organic microporous polymer is designed by introducing polar organic groups (P=O and P=S) and electron‐rich heterocyclic into the framework to obtain high carbon dioxide capture capacity. The estimated Brunauer–Emmett–Teller (BET) surface areas of these polymers are about 600 m 2 g −1 and the highest CO 2 uptake is 2.26 mmol g −1 (1.0 bar/273 K). Interestingly, the polymer containing P=O groups shows greater CO 2 capture capacity than that containing P=S groups at the same temperature. In addition, these polymers show high isosteric heats of CO 2 adsorption (28.6 kJ mol −1 ), which can be competitive with some nitrogen‐rich networks. Therefore, these microporous polymers are promising candidates for carbon dioxide capture.
