A new nanoporous porphyrin-based benzimidazole linked polymer, PBILP, was synthesized. The use of porphyrin monomers as molecular building units led to the formation of a rigid amorphous network that has a moderate surface area (SBET = 557 m2 g-1). The CO2 adsorption ability of PBILP is 12.1 wt% (2.76 mmol g-1) and it has a CO2/CH4 selectivity of 7.2 at 273 K/1 bar and a CO2/N2 selectivity of 72 at 273 K/1 bar.
