Process for the Preparation of Neutral Polyethylenedioxythiophene, and Corresponding Polyethylenedioxythiophenes

摘要

The present invention is suitable thiophene monomers in an organic solvent sikimyeo reaction with an oxidizing agent, the oxidizing agent is a neutral poly (ethylene-3,4-dioxythiophene) of using a 50 to 99.9% of the stoichiometrically required amount, the formula (1) It provides a method for producing. The resulting neutral poly (ethylene-3,4-dioxythiophene) that can be as is characterized in that which can be dissolved in an organic solvent in particular. ; Formula 1 Of ; way, ; R ¹ and R ² is 1 -C _{9 each independently of one another H or C} sub - alkyl the exhibits also, if R ¹ to represent the H, R ² is CH ₂ -OR ³ ( here, R ³ is H or C ₁ -C ₉ - an alkyl, cycloalkyl or aralkyl may be alkyl), n represents 2 to 200.
