Abstract
A new doping anion is proposed for electronically conducting polymers. Poly(3-methylthiophene) doped with bis(trifluoromethanesulfonyl)imide anions exhibits a high conductivity (460 S cm(-1)) and a remarkable s tability of the conducting state in ambient atmosphere (7% loss after 40 days). These effects are explained by the highly delocalized charge of this anion, resulting in very weak basicity and lower chemical rea ctivity.
