Abstract
A method for producing an alignment chemisorption monomolecular film having high efficiency of washing solution and being excellent in alignment property of molecules constituting the alignment monomolecular film. The method comprises the step of forming a monomolecular film by chemisorption on a hydrophilic surface of a base material by bringing the hydrophilic surface into contact with a silane-based surfactant having a carbon chain or a siloxane bond chain so as to cause a chemical reaction between them, thereby bonding one end of the surfactant molecules to the hydrophilic surface, orienting the base material in a predetermined orientation, and then vapor washing the base material in vapor of an organic solvent, and aligning molecules constituting the monomolecular film by the flow of condensation of the organic solvent formed on the surface of the base material during the vapor washing.
