Abstract

Manganese(III) porphyrins were successfully incorporated into Nafion,wherein they are located in the ionic pockets of the polymer, The results of UV-visible spectroscopy indicate that at least one solvent molecule and the anion accompany the macrocycle into the membrane, The anion is only loosely associated with the porphyrin, but strongly coordinating solvents such as pyridine remain in the axial coordination sites, Dramatic changes which were observed in the electronic and resonance Raman spectra when THF and dioxane were used as incorporation solvents indicate that the geometry of the macrocycle also changes when in Nafion, Puckering of the porphyrin ring apparently occurs as it interacts with the restrictive environment in Nafion.
