摘要:
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.

Cycloalkyl silane compounds such as cyclohexyl methyl dichlorosilane can be efficiently prepared by the photochemically induced hydrosilylation reaction. For example, an equimolar mixture of cyclohexene and methyl dichlorosilane with admixture of a catalytic amount of a platinum catalyst, which is an alcohol complex of chloroplatinic acid, is irradiated at a temperature of 70.degree. C. with ultraviolet light so that the hydrosilylation reaction takes place and proceeds almost to completeness without deactivation of the platinum catalyst to give the desired product in a yield of 90% or even higher. Unexpectedly, the efficiency of the reaction can be greatly increased when the platinum catalyst is prepared by heating a solution of chloroplatinic acid in 2-ethylhexyl alcohol at 50.degree. to 80.degree. C. for at least 4 hours.
