Self-assembled monolayers of C-60-perylenetetracarboxylic diimide-C-60 triad on indium tin oxide surface

摘要

Indium tin oxide (ITO) electrodes modified chemically with self-assembled monolayers (SAMs) of C-60-perylenetetracarboxylic diimide-C-60 triad have been designed for the first time to act as an efficient light-to-current converter in molecular devices. The monolayers were characterized using UV-Vis, X-ray photoelectron spectroscopy and atomic force microscopy. Photoelectrochemical measurement of the SAMs of C-60-Perylenetetracarboxylic diimide-C-60/ITO indicated prompt, steady, and reproducible photocurrent generation when irradiated by white light.
