摘　　要：以叔丁醇钾(t-BuOK)为催化剂,四氢呋喃(THF)为溶剂,采用去卤缩合聚合法,合成2-甲氧基-5-(2′-乙基-己氧基)-对苯乙炔(MEH-PPV)光伏材料。对反应温度、反应时间、催化剂、溶剂等条件的影响规律进行研究。结果表明,在THF作为溶剂的情况下,MEH-PPV的合成过程无需加热,且收率较高,反应过程中几乎没有凝胶现象;在反应体系中加入对甲氧基苯酚,可以控制MEH-PPV的相对分子质量,重现性良好。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.
