ABSTRACT:
According to the invention, molecules having conductive, photofunctional and other functions are secured by chemical bonds to a substrate via a chemically adsorbed monomolecular film by an adsorption process. The process comprises a step of contacting the substrate with a non-aqueous solution containing a material. The material includes a straight chain molecules having a plurality of chlorosilyl groups at both ends. A reaction occures between hydroxyl groups on the substrate surface and chlorosilyl groups at one of the ends of the material having the chlorosilyl groups. Prior to the reaction the substrate is washed with a non-aqueous organic solution by dipping the substrate in a non-aqueous solution containing molecules having a specific function for causing the reaction of the molecules with the chlorosilyl groups at the other end of the molecules having the chlorosilyl groups, thereby securing the molecules to the surface of the substrate.
