以对氰基氯苄和4,6-二氨基间苯二酚为主要原料,首先合成2,6-二(4-氯甲基苯基)苯并[1-2,4-5']二(口恶)唑,又通过2,6-二(4-氯甲基苯基)苯并[1-2,4-5']二(口恶)唑与对苯二甲醛的Wittig反应,设计合成了一种新的主链插入苯并[1-2,4-5']二(口恶)唑环的PPV聚合物(BO-PPV),通过红外光谱、核磁共振谱、凝胶渗透色谱等分析方法对其结构进行了表征.并研究了该聚合物的光电热物理特性,结果表明:该聚合物的Tg为235℃,Td为410℃,电致发光谱峰值λmax为494 nm,由ITO/BO-PPV/A1组成的单层器件在电压15伏特,发光亮度可达650 cd/cm2,发光效率0.24cd/A.
