摘要：

A porphyrin ligand with two beta-pyrrolic electron withdrawing ester groups is synthesized and its Co complex is crystallographically characterized. The iron complex of this porphyrin ligand shows an similar to 200 mV positive shift in its Fe-III/II potential in organic as well as aqueous solvents and in the onset potential of ORR relative to that of an unsubstituted porphyrin.
