In this study, PPV has been synthesized starting from the monomer p-xylylene-bis(dimethylsulphonium chloride) via sulphonium precursor route. This PPV is being used to create organic LED (OLEO) in the configuration ITO/PPV/AL and ITO/PPV/Bu-PBD/AI. In our investigation, we characterized the precursor of PPV using 1R spectroscopy and UV-Vis spectroscopy. IR spectroscopy analysis has shown that the increasing of the thermal conversion will enhance the purity of PPV. For the electrical characterization we measured the current-voltage (I-V) characteristic and determined the onset voltage of EL to find the maximum of brightness and lifetime of the devices. Futhermore, the I-V curves shown the treshold voltage of ITOIPPV/Bu-PBD/Al (-15 volt) is more higher than ITO/PPV/AI (-10 volt). From photometer analysis, we obtained for the same brightness (2,6 cd/m2) with the treshold of ITO/PPV/Bu-PBD/AI (-25 volt) and ITO/PPV/AI (-20 volt) shown the life time of ITO/PPV/Bu-PBD/AI (48 minutes) is more higher than ITOIPPV/Al (30 minutes).<p align="justify"> <br />
