Synthesis and Characterization of Porphyrin-Dimanganese Composite Molecules

Abstract The first porphyrin-dimanganese composite molecules were synthesized. Fluorescense of the porphyrin moiety was effectively quenched by the dimanganese moiety. The oxidation potentials of porphyrins showed no significant change, whereas the oxidation potentials of dimanganese moiety showed about +0.1 V shift from the porphyrin-free reference compound.
