Aromatic heterocyclic microporous polymers with high surface areas are obtained by directly crosslinking of the heterocyclic monomers under mild conditions. Owing to the narrow pore system and the heteroatom‐rich pore surface, these networks exhibit high CO 2 adsorption capacity and selectivity. At 273 K, the CO 2 /N 2 selectivity of Py‐1 is about 117, which is among the highest the reported microporous materials.
