合成了2,5-二氯甲基-1,4-二己氧基苯、1,4-二己氧基-2,5-二甲苯双(三苯基氯化季膦)和4’,4-三苯胺二醛3种单体。通过聚合反应制得了聚1,4-二己氧基对苯乙炔(DH-PPV)和含三苯胺链段的PPV类共聚物(TPA-DHPPV),对聚合物进行了结构表征和性能测试。DH-PPV和TPA-DHPPV聚合物物质结构准确,在紫外光激发下能发出强的蓝绿光,荧光光谱表征说明该类聚合物均能发射较强的荧光,电致发光器件的伏安特性测试表明该类聚合物具有较低的驱动电压和较高的发光亮度,并且该类聚合物具有较高的热稳定性。
Synthesis of 2,5-dichloromethyl-1,4-dihexyloxybenzene, 1,4-dihexyloxy-2,5-dimethylbenzene bis (triphenylphosphine chloride) and 4 ’ 4-triphenyl amine dialdehyde three kinds of monomers. Poly (1,4-dihexyloxy-p-phenylene vinylene) (DH-PPV) and PPV copolymers containing triphenylamine segments (TPA-DHPPV) were prepared by polymerization. The structures and properties of the polymers were characterized. The structures of DH-PPV and TPA-DHPPV polymers are well-structured and emit strong blue-green light when excited by ultraviolet light. The fluorescence spectra of DH-PPV and TPA-DHPPV indicate that these polymers can emit strong fluorescence and the voltammetric properties of electroluminescent devices Tests show that this type of polymer has a lower driving voltage and higher luminance, and this type of polymer has higher thermal stability.
