Abstract

original image

Geringes Erhitzen genügt, um kristallines 2,5-Dibrom-3,4-ethylendioxythiophen in ein gut leitendes, bromdotiertes Poly(3,4-ethylendioxythiophen) (PEDOT) zu überführen. Die Leitfähigkeit des Polymers kann durch Dotierung mit Iod weiter erhöht werden. Mit dieser Methode können auch dünne Filme von PEDOT mit einer Leitfähigkeit bis 20 S cm−1 auf nichtleitenden Kunststoffoberflächen einfach hergestellt werden (siehe Bild).
