SELF-ASSEMBLED MONOLAYER AND METHOD OF ITS PREPARATION

摘要

Described is a self-assembled organic monomolecular layer formed by molecules of trialkyltin on a substrate whose surface is covered with a metal selected from the group comprising gold, silver, palladium, and platinum. The monolayer is stable toward organic solvents such as n-hexane or ethanol and resists strong oxidants and reductants. Also described is a method of preparation of this organic self-assembled monolayer by adsorption of trialkylstannyl salts of trifluoromethanesulfonic, trifluoroacetic, and/or p-tolenesulfonic acids to the surface.
