Abstract

We report the preparation of highly charged nanocomposites comprised of water-soluble, anionic fullerene and cationic poly-phenylenevinylene (PPV) derivatives. The nanocomposites display high fluorescence quenching efficiency (99%) presumably due to enhanced miscibility between cationic PPV and anionic C60 via electrostatic interactions. We show that complexation between the cationic PPV and anionic C60 derivatives leads to formation of nanocomposites with optical and electronic properties distinct from individual components without preferential electrostatic interactions. Photo-induced charge transfer quenches fluorescence from the PPV component is consistent with the frontier energy offsets of PPV and C60, and cyclic voltammetry and UV-Vis spectroscopy measurements. This result confirms high miscibility between donor and acceptor and resonance Raman spectra indicate a conformational changes of the PPV backbone upon complex formation.
