| Outline of Final Research Achievements |
In general, photochemical reactions in solution occur from the lowest excited state as known as Kasha’s rule. But if rate is fast enough, various reactions will become possible even for the higher excited states and excited intermediates. For these reaction precursors, efficient reactions, which are not possible for the lowest excited state, are expected because of their higher energies. In the present research project, systematic studies on reactions from the higher excited states and excited intermediates have been carried out. In this project, we found electron transfer from the higher excited porphyrins. In addition, electron transfer from the excited radical ions has been clarified systematically. Especially, comparison with the electron transfer theory provides us characteristics of reactions from the excited radical ions. The present information will be useful to design various novel photofunctional materials.
