本發明是關於一種化合物及包含其之有機發光二極體,其組成為一種芳香族化合物結合電動傳輸與電子傳導等官能基,使之能夠克服時下材料所缺乏的低壽命高驅動電壓等特性,具有高價值與高效益的表現。有機發光二極體(OLED)型平面顯示器,相對於液晶顯示器來說具有更寬廣視角、更快的反應時間及體積更輕薄等優點,目前被應用於大面積、高亮度、全彩化之顯示。為了發展全彩化之平面顯示器,開發穩定及高發光效率之發光材料(紅色、綠色、藍色)為現今研究OLED的主要目標。然而,相較於紅色發光材料和綠色發光材料而言,藍色發光材料在發光效率和發光壽命上的開發較遲緩,因此開發新穎、具高發光效率及長壽命之藍色發光材料是目前極需努力的目標。本發明提供一種芳香族化合物,除具有藍色發光、高量子效率、優良熱穩定性之特性外,其能夠可摻雜於有機發光二極體的發光層或電洞傳輸層中,用以提升有機發光二極體的外部量子效率、最大亮度、電流效率、功率效率及其壽命,實現具有高發光效率與長壽命的有機發光二極體。 The invention of bipolar fluorescent dopants based on stilbene derivatives provides high luminous efficiency and long life due to its structure capability. An organic light-emitting diode (OLED) flat panel display has advantages such as wider viewing angle, faster reaction time, and smaller size in comparison to a liquid crystal display, and is currently applied in display having large area, high brightness, and full color. To develop a flat panel display having full color, the development of a stable light-emitting material (red, green, blue) having high luminous efficiency is the main object of current OLED research. However, in comparison to a red light-emitting material and a green light-emitting material, the development of a blue light-emitting material in luminous efficiency and emission lifetime is slower, and therefore the development of a novel blue light-emitting material having high luminous efficiency and long life is an important current object.
