Mechanism clarification and application development of photo-functional molecular materials by time-resolved spectroscopies

研究の背景 Background


Radical ions generated by the single electron transfer are considered as the important intermediates in photochemistry, material chemistry, etc. On the other hand, excitation of radical ions by photo-irradiation generates excited radical ions, which are highly reactive intermediates because of their enhanced redox potentials by excitation energy. These intermediates can be treated as the effective initiators leading to the miscellaneous new reactions, which make it possible to contribute for the conduction processes in the related various photo-functional molecular materials.

研究の目標 Outcome


Ultrafast spectroscopies using laser flash photolysis and electron beam pulse radiolysis with the broad time scales enable to observe, analyze, and control the charge dynamics. By using the time-resolved spectroscopies, our current purposes are the clarification of excited-states with charge transfer mechanisms of various reactive intermediates and the further exploration of the relevant practical application for novel conduction material systems to establish a new chemistry of these super reduction and oxidation initiators.
