| 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。

| Abstract: | 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. |
