A novel building block for donor-acceptor conjugated polymers containing perylene, poly(p-phenylenevinylene), and fullerene.

A series of new polymers containing perylene, poly(p-phenylenevinylene) (PPV) and/or pendant fullerene units have been synthesized by Wittig condensation. All of the polymers were characterized by 1HNMR, FT-IR, and GPC. The optical properties of the polymers were studied by UV-vis and FL spectra. The cyclic voltammetry showed us a good candidate for a photoinduced electron-transfer system. And the photocurrent measurement revealed an interesting phenomenon that the photocurrent increased with the contents of the fullerene in the polymers increased.
