Abstract: PURPOSE:To obtain the title composition improved in electric conductivity, moldability, cost, etc., by doping a specified polymer with a dopant. CONSTITUTION:An electrolytic solution is obtained by dissolving 0.01-0.2mol/l of a supporting electrolyte which can give a dopant which is an anion selected from among a hexafluorophosphate ion, a hexafluoroarsenate ion, a tetrafluoroborate ion, a perchlorate ion and a trifluoromethanesulfonate ion in a solvent. The title composition is obtained by doping a polymer comprising units of a monomer of the formula and prepared by, for example, polymerizing a bithiophene derivative of the formula (wherein n is 6 or greater) in the above solution in an inert atmosphere through electrolytic oxidation with 0.01-0.5mol%, based on the units of the monomer, dopant.

Abstract: PURPOSE:To simply obtain a polymer, having high electric conductivity, capable of carrying out oxidation and reduction and useful as an electrically conductive material, etc., for electronic parts by bringing a dialkoxy-bis (thienyl)silane into contact with iron chloride. CONSTITUTION:A dialkoxy-bis(2-thienyl)silane of formula I (R'' and R'' are alkyl) [e.g. diethoxybis(2-thienyl)silanel is brought into contact with iron(III) chloride to afford the objective polymer having a recurring unit of formula II. The reaction is preferably carried out at ambient temperature or a slightly heated temperature by dissolving the compound of formula I in an inert solvent and then adding iron(111) chloride powder to the resultant solution. This compound of formula I is preferably obtained by reacting a thiophene having the 2-position substituted with an alkali metal such as 2-lithiothiophene with a dihalodialkoxysilane used at 2:1 molar ratio in an inert solvent at -10 to $40 deg.C in an inert atmosphere.

Abstract: NEW MATERIAL:A compound expressed by formula I ((n) is >=2). EXAMPLE:3-(3-Phenylpropyl)thiophene. USE:An organic electronic material. PREPARATION:A 3-halogenothiophene expressed by formula II (X is halogen) is allowed to react with a Grignard reagent expressed by formula III to provide a thiophene expressed by formula I, which is then subjected to oxidative polymerization or electrolytic polymerization to provide the polymer expressed by formula IV. The polymer expressed by formula IV is soluble in organic solvents and suitable as an organic conductive material having processability. Since the polymer expressed by formula IV has a regular head-to-tail structure, high functionality can be expected.

Abstract: PURPOSE:To obtain an organic conductor which can be widely applied in the field of electronics, by electrolytically polymerizing an organic conductor based on a specified organic polymer. CONSTITUTION:An organic conductor based on an organic polymer of the formula (wherein l is 1-6, m is 0-2, and R is a 1-6C linear alkyl, and n is 10-300) is produced by an electrolytic polymerization process comprising immersing a working electrode and a counter electrode in a solution formed by dissolving a polymerizable monomer such as an aromatic compound and a supporting electrolyte for applying a current in an organic solvent such as propylene carbonate, and applying a current across the electrodes. As the solvent, acetonitrile, propylene carbonate or nitrobenzene is particularly desirable. The polymerization temperature is preferably 0-10 deg.C, and the current density is preferably 1-55mA/cm . The polymerization is preferably carried out in a polymerization atmosphere of an inert gas such as nitrogen or argon.
