The molecular system is composed of two types of helical peptides that carry different chromophores and have different directions of dipole moments when they are immobilized on gold. The mixed, self-assembled monolayer generated an anodic photocurrent when one of the two chromophores was photoexcited, whereas the photocurrent switched to being cathodic when the other chromophore was photoexcited. The opposite current response arises from the dipole moment of each helical peptide, which accelerates electron transfer in the same direction.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699996339857282","@type":"Researcher","foaf:name":[{"@value":"Shiro
