Two-Dimensional Highly Ordered Molecular Layers Prepared by Adsorption-Induced Self-Organization

Abstract

Adsorption-induced self-organization is a new concept for “wet process” techniques for preparing highly ordered molecular adlayers by spontenious adsorption in aqueous solution. The essential step is a controlled “mild” adsorption, which makes possible rapid surface diffusion and adsorption/desorption equilibrium. To conduct “mild” adsorption, the choice of substrate and setting of electrode potential are most possible. STM visualization of highly ordered molecules provides fundamental data on intermolecular interactions.
