    The monolayers of pureC60 derivative (C60-COOH) are stable on the surface of purewater subphase and poly-phenylene-vinylene derivative (PPV) solution, respectively. The composite ultrathin film of PPV and C60-COOH was successively fabricated on the quartz and mica substrate by using Langmuir-Blodgett technique. X-ray photoelectron spectrometry (XPS) measurements show that the PPV is embedded into the film during the fabrication process. The surface morphologies of pure C60-COOH film and the composite film were investigated with atomic force microscopy (AFM), respectively. The phenomenon of electron transmission between PPV and C60-COOH in the composite film was confirmed by UV-vis spectra.
