摘要： 利用强碱诱导的去卤缩合聚合法,合成了不对称烷氧基取代的聚(2-甲氧基-5-十二烷氧基-1,4-对苯乙炔)(PMDPV).其溶解性和成膜性能优于对称取代的聚(2,5-双十二烷氧基-1,4-对苯乙炔).以PMDPV为发光层质的聚合物电致发光器件,其发光峰值波长为605nm.并用IR、UV-Vis、TGA、1H NMR、GPC等对所合成的聚合物进行了表征。

关键词: 聚甲氧基十二烷氧基对苯乙炔, 电致发光聚合物, 合成, 去卤聚合法

Abstract: Poly(2-methoxy-5-dodecyloxy-1,4-phenylenevinylene)(PMDPV) was prepared via dehydrochlorination process, induced by potassium tert-butoxide in tetrahydrofuran. It showed a better solubility and film forming property than poly(2,5-didodecyloxy-1,4-phenylenevinylene). The peak wavelength value of EL cell based on PMDPV was 605 nm. The structure of the polymer was characterized by IR, UV-Vis,1H NMR, TGA and GPC.

Key words: poly(methoxy-dodecyloxy-phenylenevinylene), electroluminescent polymer, synthesis, dehydrochlorination
