摘　　要：通过经典的Wittig反应,成功合成了聚对苯亚乙烯和2种分子量聚氧化乙烯的多嵌段共聚物(PPVEO200和PPVEO600)。PPVEO600较PPVEO200显示出了更好的热性能和电致发光性能,其聚集态为一种通过物理交联点而形成的网状结构,热分析表明,该聚合物玻璃化温度为-463℃,其N2气环境下的热分解温度达350℃。电化学掺杂之后,基于共聚物PPVEO600的发光电池器件结构为ITO/PPVEO600+LiClO4/Au,起亮电压为26V,32V时最大电致发光效率为213cd/A。Multi block copolymer poly( p phenylene vinylene co poly(ethylene oxide))(PPVEO200 and PPVEO600) was synthesized by Wittig reaction. PPVEO600 showed better thermal and electroluminscence properties than PPVEO200, and the aggregated structure of PPVEO600 was reticulated through physical crosslinking point. PPVEO600 exhibits a glass transition temperature of -46 3 ℃, and shows high conductivity after electrochemically doped with LiClO 4 . The LEC device (ITO/PPVEO600(LiClO 4 )/Au) was fabricated , which showe...
