摘要
Core-and valence-level X-ray photoemission spectra of three iron phthalocyanines (monomer, dimer, and polymer) are interpreted and related with the catalytic activity of these compounds in the electrochemical reduction of oxygen. EPR data are also reported for the three species. The iron spin and oxidation state, the electron delocalization in the organic ligand, and the covalent character of the Fe-O2 bond are found to be important factors in the catalytic process. © 1979, American Chemical Society.
