Electrochemical and UV-Vis/ESR spectroelectrochemical properties of thienylenevinylenes substituted by a 4-cyanostyryl group

Journal Article


Abstract


  • The -electron delocalisation in conjugated thienylenevinylenes bearing arylethenyl chromophores,

    makes those materials interesting candidates for electro-optic applications. In this study, we

    report the results of electrochemical and UV–Vis/ESR spectroelectrochemical studies of a pair of

    thienylenevinylenes substituted by the 4-cyanostyryl group, bearing either a hydrogen, or methyl group

    terminated carbons at the peripheral thiophene rings. The reactivity of various functional segments of

    investigated molecules was assessed by comparing the reactivity of the protected and unprotected counterparts

    and the behaviour of their electrooxidation products. For the capped derivative, two irreversible

    anodic redox processes giving electrochemically inactive products were observed, while the uncapped

    molecule yields electroactive materials already upon its first oxidation step.
