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.
