Abstract

Continuing investigations of copper(II) and iron(II) protoporphyrin complexes show that variations in solvent polarity, number of coordinating ligands and spin state for iron(II) can induce changes in the electronic relaxation rates of the protoporphyrin complexes studied. Picosecond biphasic kinetic behavior indicates that intermediate energy levels are present in both copper(II) and iron(II) complexes.
