Notes:
Redox-active fullerenes can be covalently bound to a variety of donors, their photophysical properties have been investigated. Their photochemical processes. Including electron transfer and energy transfer, are varied, depending on the donor, linkage between the donor and C60, and solvent. Regardless of the solvent and linkage, the charge-separated state is produced efficiently in zinc porphyrin-C60 systems, showing that C6o is a good electron acceptor. The most intriguing characteristic of C60 in electron transfer is that C60 accelerates photoinduced charge separation and retards charge recombination in the dark. The long-lived charge-transfer state: of the C60-porphyrin dyad was successfully converted to photocurrent using a self-assembled monolayer technique. These findings will provide a new strategy for the design and synthesis of artificial photosynthetic systems and photoactive materials using C60 as a building block.
