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 CO2 adsorption capacity and selectivity. At 273 K, the CO2/N-2 selectivity of Py-1 is about 117, which is among the highest the reported microporous materials.
