Conductive organic thin film, process for producing the same, electronic device employing the same, electrical cable, electrode, pyrrolyl compound, and theienyl compound

A method for manufacturing a conductive organic thin film, comprising:

• forming an organic thin film, by bringing a compound made of organic molecules including, at one end, a terminal bonding group that can be covalently bonded to a substrate surface, a conjugated bondable group that is located at any portion of the organic molecules and that can be 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 conjugated bondable group, into contact with a substrate whose surface has active hydrogen or to which active hydrogen has been added, and covalently bonding the two through an elimination reaction;
• either orienting the organic molecules making up the organic thin film by tilting them in a predetermined direction or by giving them orientation while polymerizing them in a subsequent polymerization step;
• and
• in a polymerization step, conjugatively bonding the conjugated bondable groups to one another by at least one polymerization method selected from polymerization through electrolytic oxidation, catalytic polymerization, and polymerization through energy beam irradiation, so as to form a conduction network.
