Iron containing porous organic polymers (Fe-POPs) have been synthesized by a facile one-pot bottom-up approach to porphyrin chemistry an extended aromatic substitution reaction between pyrrole and dialdehydes in the presence of small amount Fe(III). The Fe-POPs possess very high BET surface area, large micropores showed excellent CO(2) capture (~19 wt%) at 273 K/1 bar.
