Self-assembled monolayers (SAMs) of alkanethiols on gold have been one of the most well studied systems. The SAM with a photoactive group and an electron relay group formed on a metal electrode in a solution containing an electron acceptor and/or donor should be a good candidate for a stable, efficient photoconversion device where up-hill photoinduced electron transfer, i.e., photocurrent generation, takes place. We have achieved a control of a direction of photoinduced electron transfer and a very efficient photocurrent generation at the gold electrodes modified with the SAMs of porphyrin-quinone-thiol and porphyrin-ferrocene-thiol linked molecules.
