The invention relates to novel polythiophene-polyanion complexes which are soluble or dispersible in nonpolar organic solvents, and to the use thereof.

Polythiophene polyanion complexes in homopolar organic solvents

An aqueous dispersion used for producing a conductive film is provided. The dispersion contains a complex of poly(3,4-dialkoxythiophene) and a polyanion, and is produced by polymerizing 3,4-dialkoxythiophene in an aqueous solvent in the presence of the polyanion by using peroxodisulfuric acid as an oxidizing agent or by using an oxidizing agent and an acid that is employed so as to lower pH of the reaction mixture.

The invention relates to a process for the purification of thiophenes by means of precipitation. The purified thiophenes are liquid at room temperature, have a purity of at least 99.50 wt. %, and are represented by the following general formula (I), wherein Rand Rindependently of each other are, for example, a linear or branched C-C-alkyl group, or together form a fused C-C-dioxyalylene ring. The process involves: (I) precipitating the thiophene by cooling a solution of the thiophene and at least one solvent; or (II) precipitating the thiophene by adding the thiophene to a cooled solution of solvent and optionally the thiophene. The solutions are cooled to a temperature below the melting point of the thiophene.

The present invention provides a method for the production of an aqueous dispersion containing an electroconductive polymer component which enables electroconductive thin films which are outstanding in their transparency and electroconductivity to be formed, together with the aqueous dispersion obtained by said method. This method includes a stage in which a 3,4-dialkoxythiophene is polymerized in an aqueous solvent using an oxidizing agent in the presence of a polyanion and, in this stage, said oxidizing agent is added by the dropwise addition of a solution or dispersion containing said oxidizing agent to the reaction solution or, alternatively, in the polymerization stage, the alkali metal ion concentration in the reaction liquid is maintained at no more than 400 ppm.
