Synthesis of Oligophenylenevinylene Heptamers Substituted with Fullerene Moieties

Oligophenylenevinylene (OPV) derivatives substituted with one or two fullerene subunits have been prepared starting from a fullerene carboxylic acid derivative and OPV heptamers bearing one or two alcohol functions. The electrochemical properties of the resulting C60-OPV derivatives have been investigated by cyclic voltammetry. Whereas the fist reduction of both C60–OPV conjugates is centered on the C60 unit, the oxidation is centered on the OPV rod. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
