This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution license (http://creativecommons.org/licenses/by/4.0/).; International audience; Two arylene-cyanovinylene isomers formed by a phenyl unit substituted in para or meta positions by two cyanovinylene-methylthiophene were synthesized. Their main physicochemical properties were studied in order to point out the influence of the nature of the substitution (para vs meta) of the central phenyl unit on the electronic properties of the two isomers. The anodic electropolymerization of the two compounds was also studied with a main emphasis on the electrochemical behavior of the derived polymers showing that the specific behavior of the para-substituted isomer is maintained in its polymer leading to a polymer with a lower bandgap (1.95 eV) than the polymer obtained from the meta-substituted isomer (2.16 eV).
