A new monomer containing coronene diimide with diphenylamine end groups (DCTD) has been synthesized and polymer thin films were electropolymerized onto gold, glassy carbon and ITO electrode surfaces. The resulting polymers show a reversible 2e(-) oxidation of the diphenylbenzidine unit and reversible reductions of the aromatic diimide. AFM was used to characterize the polymer film morphology. The electronic and electrochromic properties of these films were evaluated for use in organic electronic applications. (c) The Author(s) 2018. Published by ECS.
