| Research Abstract |
In this study, 3_<10>-helical peptides carrying a disulfide group at the N-terminal, linearly-arranged six naphthyl groups at the side chains, and an energy acceptor at the C-terminal were immobilized on a gold surface via a gold-sulfur linkage to form a well-defined self-assembled monolayer with vertical orientation. Upon photoexcitation of the naphthyl groups of the monolayers in solutions containing an electron donor, all the monolayers generated an anodic photocurrent. Detailed discussion on photoenergy and electron transport processes shows a prospect to realize efficient photocurrent generation systems taking advantages of both light-harvesting and charge-transport functions in the future.
