Porphyrin based porous organic polymers: novel synthetic strategy and exceptionally high CO2adsorption capacity

Iron containing porous organic polymers (Fe-POPs) have been synthesized by a facile one-pot bottom-up approach to porphyrin chemistry by an extended aromatic substitution reaction between pyrrole and aromatic dialdehydes in the presence of small amount of Fe(III). The Fe-POPs possess very high BET surface area, large micropores and showed excellent CO2 capture (∼19 wt%) at 273 K/1 bar.
