Abstract
Water-soluble cobalt complexes have shown great potential in fuel-cell technology, water purification, and on-site nerve-agent deactivation or decomposition because of their ability to reversibly bind oxygen. The presence of halogens (F, Br, Cl) at the porphyrin's pyrrole carbons creates an electron-deficient ligand which we anticipate will increase the metal ion’s potential to bind with oxygen. Halogenation was possible either via fluorination of pyrrole porphyrin precursors or via bromination/chlorination of the porphyrin moiety. To render the porphyrin ionic and water-soluble, methylation of the aminophenyl substituents was conducted using methyltrifluoromethylsulfonate. Results indicate that porphyrin behavior varies depending on the halogenated substituent.
