Description

一种含蒽类衍生物、 其制备方法及有机电致发光显示器件 技术领域
本发明涉及显示技术领域, 尤指一种含蒽类衍生物、其制备方法及有 机电致发光显示器件。 背景技术
目前, 有机电致发光显示器件 ( Organic Electroluminesecent Display, OLED )与传统的液晶显示器件( Liquid Crystal Display , LCD )相比, 由 于具有响应快、 色域广、 超薄、 能实现柔性化等特点, 已经逐渐成为显示 领 i或的主流。
OLED显示器件的基本结构包括衬底基板,制作在衬底基板上的有机 电致发光元件;其中,每个有机电致发光元件包含相对设置的阴极和阳极 , 以及位于阴极和阳极之间的有机发光层。 OLED显示器件的发光是通过在 阳极和阴极之间施加电压,阳极中的空穴与阴极中的电子在有机发光层复 合形成激子, 激发态激子转变到基态, 激发有机发光层中的有机发光材料 发光来实现的。有机发光材料根据发光机理可以分为两种: 一种是由利用 单线态激子发光的荧光材料组成,另一种是由利用三线态激子发光的磷光 材料组成。
在 OLED显示器件中, 为了提高所形成的 OLED的发光效率和稳定 性,有机发光层可包含分别由不同有机材料形成的空穴注入层、 空穴传输 层、 发光层、 电子传输层、 电子注入层等膜层。 为提高有机发光层的发光 效率,可在发光层的主体材料中掺杂比主体材料具有更高量子产量的掺杂 材料。这是因为激发态激子具有将其能量转移给重新组合部位附近的材料 中具有更小带隙的材料的倾向。 因此, 掺杂材料选自于比主体材料具有更 高的量子产量和更小的带隙(更大的波长)的材料; 否则, 激发态激子的 能量将转移至具有更低量子产量的主体材料,由此产生弱的发射或者不发 射。
为了提高 OLED 显示器件中有机发光层的发光效率和发光亮度, 提 供一种稳定且高效率的有机发光材料应用于 OLED显示器件的有机发光 层, 已成为本领域技术人员亟需解决的问题。 发明内容
