我們成功的合成出側鏈官能基含對苯歐唑發光團的PPV高分子MVBMEH-PPV(Ⅰ) 與MVBBEH-PPV(Ⅱ) 具有放紅光的發光特性，且對一般做旋轉塗佈的溶劑皆具有良好的溶解度。我們利用Horner-Wadsworth-Emmons的方法進行縮合聚合，合成不同結構的交互共聚高分子。並將交互共聚高分子當成發光層，以ITO玻璃基板為陽極，鎂與銀為陰極，製作單層高分子發光二極體，其元件放光光譜MVBMEH-PPV (Ⅰ) 與MVBBEH-PPV (Ⅱ) 分別為641nm、624 nm，起始電壓分別為4.4伏特與8伏特為放紅光的元件。

We present synthesis and characterization of benzothiazole contained pendent PPV polymers. In this study, polymers of MVBMEH-PPV(Ⅰ) and MVBBEH-PPV (Ⅱ) have been synthesized through the well - known Horner-Wadsworth-Emmons polycondensation reaction. The synthesized polymers were completely soluble in common organic solvent, such as THF, toluene and chloroform etc. The polymer devices of MVBMEH-PPV(Ⅰ) and MVBBEH-PPV(Ⅱ) have relative low turn-on voltage at 4.4 Volts and 8 Volts. The EL spectrum of MVBMEH-PPV (Ⅰ) and MVBBEH-PPV (Ⅱ) exhibits the emission peak at 641 nm and 624 nm, which represent deep red and red respectively.
