摘要：
Phase-separated binary self-assembled thiol monolayers of 2-mercaptoethanesulfonic acid and 1-octadecanethiol have been studied by cyclic voltammetry and scanning probe microscopy. Cyclic voltammograms for the reductive desorption of the binary self-assembled monolayers show a high degree of phase separation of the monolayers. The presence of two different types of domains caused by phase separation is imaged by atomic force microscopy.
