Outline of Final Research Achievements

In the present study, photoinduced electron transfer reaction of zinc(II) porphyrin complex bearing electron accepting or electron donating moiety at the periphery of the porphyrin complex was studied using various spectrophotometric techniques, and the factor for producing the long-lived charge-separated intermediate states and the possibility of these charge-separated states for utilization as a chemical energy conversion system were investigated. A zinc(II) porphyrin complex bearing a bipyridine moiety at the periphery was found that the photoinduced electron transfer from the excited state of the porphyrin to the bipyridine moiety in the presence of excess Cu(II) ion was observed using a transient absorption technique. Relatively long lifetime of these charge-separated states was discussed in terms of the molecular structure of the porphyrin complex.
