The MEH-PPV electroluminescent materials were synthesized by the dehalogenation condensation method using potassium t-butoxide as the catalyst and tetrahydrofuran as the solvent.The effects of reaction temperature,reaction time,catalyst,solvent and other conditions were studied in details.The synthesis of MEH-PPV requires no heating and the yield is good when THF as the solvent in room temperature.And no gelation appeared during the reaction.The relative molecular mass of MEH-PPV could be controlled well by adding p-methoxyphenol in the reaction system.
