利用脱氯化氢的方法合成了聚(2-甲氧基-5-己氧基)对苯乙炔(PMOHOPV)、聚(2-甲氧基-5-辛氧基)对苯乙炔(PMOCOPV)、聚(2,5-二丁氧基)对苯乙炔(PDBOPV)、聚(2,5-二己氧基)对苯乙炔(PDHOPV)、聚(2,5-二辛氧基)对苯乙炔(PDCOPV)等5种聚合物发光材料.通过核磁和红外表征了它们的结构.通过热失重曲线考察了它们的热稳定性.并从温度、催化剂、反应时间、烷氧基取代等方面考察了对聚合物溶解性、分子量、发光性能等的影响.发现可以通过催化剂的用量来改变聚合物分子量,聚合物的分子量与聚合物的溶解性成正比.
Five kinds of PPV derivatives(poly(2-methoxy-5-hexyloxy1,4-phenylene vinylene)(PMOHOPV),poly(2-methoxy-5-octyloxy-1,4-phenylene vinylene)(PMOCOPV),poly(2,5-dibutyloxy-1,4-phenylene vinylene)(PDHOPV),poly(2,5-dihexyloxy-1,4-phenylene vinylene)(PDHOPV),poly(2,5-dioctyloxy-1,4-phenylene vinylene)(PDCOPV))are prepared by dehydrochlorination process with p-methoxyphenol and p-diphenol as raw materials.In comparison with PPV,the five kinds of PPV derivatives can resolve in organic solvent.The influences of synthe... |
