Synthesis of oligophenylenevinylene heptamers substituted with fullerene moieties

摘要

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 C-60-OPV derivatives have been investigated by cyclic voltammetry. Whereas the fist reduction of both C-60-OPV conjugates is centered on the C-60 unit, the oxidation is centered on the OPV rod. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 6945t Weinheim, Germany, 2008).
