摘要: 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。Abstract: 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
