Description
本發明係關於一種有機發光二極體,並且特別地,本發明關於一種具有藍光發光化合物之有機發光二極體。
伴隨多媒體技術之發展,平板顯示裝置(Flat Panel Display,FPD)之重要性得到加強。響應於此種趨勢,多種顯示裝置例如一液晶顯示裝置(Liquid Crystal Display,LCD)、一電漿顯示面板(Plasma Display Panel,PDP)、一場發射顯示器(Field Emission Display,FED)、以及一有機發光二極體顯示裝置已經得到實際應用。
在這些顯示裝置中,有機發光二極體裝置係為一種按照如下方式發射光線的自發光裝置:電荷注入於一電子注入電極(陰極)與一電洞注入電極(陽極)之間的有機層中,電子與電洞配對,並且然後消失用以產生光線。
有機發光二極體裝置具有一些優點:其可形成於一可撓性透明基板(例如,塑料基板)之上且可在一相比較於電漿顯示面板(PDP)與無機發光二極體顯示裝置之作業電壓更低的電壓下(例如,10伏或更低)作業。有機發光二極體還可具有例如相對低的功率消耗及優良顏色再現的其他優點。進一步而言,由於有機發光二極體裝置可發射三種顏色(即,綠色、藍色以及紅色)之光線,因此有機發光二極體裝置可看作能夠顯示不同顏色之影像的下一代全色彩顯示裝置。
一藍色有機發光二極體裝置能夠透過順次堆疊一陽極、一電洞注入層、一電洞傳輸層、一發射層、一電子傳輸層、一電子注入層、以及一陰極形成。雖然發射層使用一基質摻雜系統,但是按照慣例使用的摻雜材料表現出相對高驅動電壓及低發射效率。
因此,需要開發一種具有新結構的摻雜材料,以使得有機發光二極體裝置獲得高亮度及高效率。
因此,鑒於上述問題,本發明之一方面在於提供一種藍光發光化合物及具有該化合物之有機發光二極體,此有機發光二極體能夠具有高亮度及高效率。
本發明之一實施例之藍光發光化合物可具有以下化學式1之結構:
其中A1、A2、以及A3分別自氫、一取代或未取代芳基、一雜環基、以及一脂肪基中獨立選擇。
以下將結合圖式部份詳細描述本發明之實施例。
