摘要：

A self-assembled monolayer (SAM) composed of a dialkyl compound carrying an N-ethylcarbazolyl (ECz) group and a helical peptide carrying an anthryl (Ant) group was prepared on gold. The photocurrent magnitude of the bicomponent SAM in the presence of an electron acceptor was larger than that of the unicomponent SAMs. The efficient photocurrent generation of the bicomponent SAM is due to the integration of the photoenergy-harvesting and electron-transport systems.
