主链含三苯胺单元的聚苯乙炔的合成及其电致发光性能

Syntheses and Properties of Polyphenylenevinylene with Triphenylamine Segment in the Polymer Backbone

采用4-甲基三苯胺的二醛基化合物分别与对、间、邻 二甲基苯的膦盐反应,制备了三种含三苯胺单元的聚苯乙炔类共聚物TPA PPV、TPA PmPV和TPA PoPV。结果表明:TPA PPV和TPA PmPV具有良好的热稳定性和光电化学性能,该类共聚物不但具有良好的空穴传输性能,而且作为发光材料应用于发光器件时可以调制发光颜色。

Three copolymers: poly( p -phenylenevinylene), poly( m -phenylenevinylene) and poly( o -phenylenevinylene) containing triphenylamine segment (TPA-PPV,TPA-P m PV and TPA-P o PV) were synthesized. Their photochemical and electrochemical properties were also studied. The results show that TPA-PPV and TPA-P m PV are good hole-transport and emission materials used as active layer in EL devices.
