| Abstract;Reorganization energies of porphyrin-C60 linked systems have been determined by analyzing the charge-transfer emission in benzene. The reorganization energies are estimated as 0.1-0.2 eV, which are comparable to the smallest ones in the photosynthetic reaction center. A light harvesting model, boron dipyrrin, has been combined with a reaction center model, ferrocene-porphyrin-fullerene triad, to construct integrated artificial photosynthetic assemblies on a gold electrode using mixed monolayers of the respective self-assembled unit. The architecture on the gold electrode has established a cascade of photoinduced energy transfer and multistep electron transfer, leading to the production of photocurrent as an output with the highest quantum yield (50.+-.8%) ever reported for photocurrent generation at monolayer-modified metal electrodes using donor-acceptor linked molecules.
