ABSTRACT:
Disclosed are a conductive pyrrole derivative monomolecular film covalently bonded to a substrate surface and method of manufacturing the same, and a monomer used for forming the conductive pyrrole derivative monomolecular film and method of manufacturing the same. The invention relates to a monomolecular ultrathin film comprising 1-pyrrolyl groups and silicon groups. The monomer used for forming the film is provided by reacting .omega.-(1-pyrrolyl)-1-alkene compound to a monosilane derivative compound, in which three out of four hydrogen atoms of monosilane are replaced with halogen or alkoxy groups, in the presence of a transition metal catalyst. A substrate is dipped and held in a nonaqueous solution of the above-noted monomer, thus chemically bonding a monomolecular film to a substrate surface. Furthermore, a polypyrrole derivative ultrathin film is formed by the electrolytic or catalytic polymerization of the monomolecular film.
