CONDUCTIVE ORGANIC THIN FILM, PROCESS FOR PRODUCING THE SAME, ELECTRONIC DEVICE EMPLOYING THE SAME, ELECTRICAL CABLE, ELECTRODE, PYRROLYL COMPOUND, AND THEIENYL COMPOUND

摘要

A conductive organic thin film which is made up of organic molecules each having at one end a terminal bonding group bonded to a substrate surface by covalent bonding and having a conjugated bond group which is present anywhere in the organic molecule and has been polymerized with other molecules and a polar functional group which contains no active hydrogen atom and is present anywhere between the terminal bonding group and the conjugated bond group, the organic molecules being oriented and the conjugated bond groups having been polymerized to form a polymer and a conductive network. The conductive organic thin film in an undoped state has a conductivity (ς) as measured at room temperature (25 °C) of 5.5x105 S/cm or higher, preferably 1x107 S/cm or higher. It has a far higher conductivity than metals such as gold and silver. In particular, a polypyrrole or polythienylene film formed by electrolytic oxidative polymerization and based on conjugated bonds has a high conductivity.
