A method for producing a conductive polymer-containing dispersion, the method including a polymerization step of subjecting a monomer that is to be a constitutional unit of a conjugated conductive polymer to a polymerization reaction in a mixed solution containing the monomer, a polyanion, and a dispersion medium to produce a polymerized product; and a dispersion treatment step of performing a dispersion treatment on a reaction solution obtained in the polymerization step to prepare a dispersion of the polymerized product, wherein a dispersion medium is added one or more times at any point in time from after the polymerization step to during the dispersion treatment step to make a mass concentration (B) of the polymerized product in the dispersion after the dispersion treatment step lower than a mass concentration (A) of the polymerized product in the reaction solution.

The synthesis of ring brominated long-chain 2-alkoxythiophenes is reported, involving mild (Oxone) oxidation of readily prepared 2-thienyltrifluoroborate salts followed by Mitsunobu etherification. Both procedures are operationally straightforward and use inexpensive reagents. Using this approach, several novel mono- and dibrominated octyloxythiophenes with previously elusive substitution patterns
