摘要：

Charge-transfer composite material, poly-1-methoxy-4-octoxy-(para-phenelene vinylene) (MO-PPV) wrapped single wall carbon nanotubes (SWNTs), MO-PPV/SWNTs, was synthesized by in situ polymerization. Photophysics properties of MO-PPV/SWNTs were studied by using steady-state spectra, femtosecond fluorescence up-conversion technique, and streak camera. Compared with the pure MO-PPV in solution, fluorescence quenching was observed. Photoinduced electron-transfer from MO-PPV to SWNTs occurs on femtosecond timescale, while photoinduced intermolecular energy-transfer appears at similar to 100 ps timescale. (C) 2007 Elsevier B.V.
