摘要
通过Wittig反应成功地合成了一种新型的聚对苯乙烯和长链聚氧化乙烯的嵌段共聚物(PPVPEO600).该共聚物在常温下为无定形结构,并可旋涂形成均一稳定的薄膜;玻璃化转变温度为-46.3°C,N2环境下热分解温度达359°C;可以直接掺杂锂盐制备结构为ITO/PPVPEO600(LiClO4)/Au的发光电化学池器件,起亮电压为2.6V,其发光波长在蓝绿光范围内,有2个峰值分别是458和485nm.
Luminescence block copolymer poly(p-phenylene vinylene) with polyethylene oxide (PPVPEO-600) was successfully synthesized through the Wittig reaction. PPVPEO600 is highly soluble in common organic solvents and can be spin-coated onto various substrates to give highly homogeneous thin films. It is amorphous at room temperature. PPVPEO600 shows a glass transition at -46.3°C and its degradation temperature is 359°C under nitrogen atmosphere. The PLECs device based on this copolymer was successfully fabricated and the structure is ITO/PPVPEO(LiClO4)/Au. It shows a turn-on voltage at 2.6 V for both current and light emission. Its EL maximum emission peaks appear at 458 nm and 485 nm respectively. PPVPEO600 can be used as a blue light emission material.
