Conductive organic thin film, method for manufacturing the same, and electronic device, electric cable, electrode, pyrrolyl compound, and thienyl compound using the same

摘要

It is an object to provide a conductive organic thin film having organic molecules that include at one end a terminal bonding group that is covalently bonded to a substrate surface, a conjugate bonding group that is located at any portion of the organic molecules and that is polymerized with other molecules, and a polar functional group that does not include active hydrogen and that is located at any portion between the terminal bonding group and the conjugate bonding group, wherein the organic molecules are oriented and their conjugate bonding groups are polymerized, forming a conduction network. The conductivity (rho) of the conductive organic thin film at room temperature (25° C.) is at least 5.5x10⁵ S/cm, and preferably at least 1x10⁷ S/cm, without dopants, having significantly higher conductivity than metals such as gold and silver. In particular, a film of polypyrrole or polythienylene conjugate bonds that is polymerized through polymerization through electrolytic oxidation has high conductivity.
