Abstract:Photochemical hole burning by photoinduced electron transfer was studied with emphasis on the effects of sacrificially consumable molecules. A backward electron-transfer process reduces the total efficiency of electron transfer. In order to enhance the effective electron transfer and to suppress the backward electron transfer, sacrificially consumable molecules were introduced to the donor—acceptor electron-transfer systems. In the presence of sacrificially consumable molecules, the efficiency of hole formation increased remarkably. The two-color enhancement of hole formation was also observed for a suitable acceptor.
