Abstract:The electronic and optical properties of conductive polymers (CPs) are related to the formation of polarons and bipolarons localized along the polymer backbone. Their concentration is affected by the conformational and morphological features of the CPs, making it crucial to understand how they are affected by chain conformation and π-electron delocalization. In this work, we studied the modulation of the concentration of polarons and bipolarons in PEDOT:PSS after post-treatment with hydrazine and H 2 SO 4 , wh… Show more
