主链含三苯胺链段的TPA-DHPPV共聚物的合成及表征

Synthesis and properties of TPA-DHPPV copolymers containing triphenylamine in main chain

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。

1,4-dihexyloxy-2,5-dichloromethanebenzene monomer, 1,4-dihexyloxy-2, 5-dimethane （dichlorotriphenyl-phosphine） monomer and 4,4＇-dialdehyde triphenylamine monomer were synthesized. 1,4-dihexyloxy-poly（phenylenevinylene） （DHPPV）, DHPPV copolymers containing triphenylamine （TPA-DHPPV） were synthesized through reaction, and their structure and properties were characterized. Structures of DH-UV-V is exact, launch strong fluorescence in fluorescence spectrum, have low slaving voltageand high light Brightness, and have high thermostability.
