An oligophenylenevinylene (OPV) derivative substituted with two fullerene subunits has been prepared starting from a fullerene carboxylic acid derivative and an OPV heptamer bearing two alcohol functions. Photophysical investigations have revealed the occurrence of intramolecular photoinduced energy- and electron-transfer processes in this hybrid compound.

lacking the fullerene unit (Δλmax = 24 to 34 nm). Whereas the absorption properties are dramatically affected by the intramolecular electronicinteractions between the conjugatedbridging system and the accepting C60 spheroid, cyclic voltammetry revealed only small changes in their redox potentials. However, these intramolecular interactions have a significant influence on the electronic coupling of

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
