ABSTRACT:
A process for producing an organic device includes forming a first electrode and a second electrode on a substrate having an insulating film formed on a surface thereof, etching out the insulating film with the first electrode and the second electrode being used as masks, forming a monomolecular or built-up monomolecular film containing electrolytically polymerizable unsaturated groups directly or indirectly on the surface of the substrate by a chemical absorption method or the Langmuir-Blodgett method. The process further includes a procedure of spreading a surfactant containing the electrolytically polymerizable unsaturated groups on the surface of a water bath to form a monomolecular film, transferring at least one layer of the monomolecular film into the surface of the substrate, and chemically bonding molecules of the surfactant to form at least one layer of the monomolecular film of the surfactant containing electroconductive conjugated groups, applying a voltage between the first electrode and the second electrode to polymerize the electrolytically polymerizable unsaturated groups, and deriving a third electrode from the substrate such that the substrate acts as the third electrode.
