Abstract
本发明属于有机电致发光材料领域,公开了一种咔唑化合物及其应用。本发明所公开化合物具有通式(I)所示的结构,且在其结构中至少包括一个氘原子。相对于非氘代的主体材料而言,以本发明所提供的咔唑化合物制备的有机电致发光器件,其量子效率较高,效率滚降得到了明显的抑制,因而本发明的化合物非常适合用于作为有机电致发光器件中的蓝色磷光主体材料。
Description
技术领域
本发明属于有机电致发光材料领域,特别涉及一种咔唑化合物及其应用。
背景技术
有机电致发光器件,是通过在阴极和阳极引入一层或多层有机膜,实现加电发光的一种器件技术,能够实现超薄、柔性以及透明的性能,在平板显示及照明行业的应用逐年提高。
为了实现不同的目标,有机电致发光器件的结构也是多种多样的。对于发射光谱的发光层,一种方式是采用主客体掺杂的形式进行效率和寿命的提升。主体材料接收能量并传递给客体,客体材料接收能量后发射相应的光谱。不同的主体和客体材料,可以实现不同颜色的发光。根据自旋统计规律,在OLED器件中由阴阳两极注入的电子和空穴复合产生的激子有25%是单线态,75%是三线态。只有采用磷光材料,才有可能利用全部的激子达到100%的内量子效率,从根本上提高OLED的效率。
磷光来自于物质的三重激发态,在室温固态下,一般有机化合物材料的磷光发射很微弱,而过渡金属如Ir3+、Pt2+等的配合物具有强的磷光发射。此类材料具有热稳定性好、光色可调、发光效率高及磷光寿命短等优点,故而成为电致磷光发光材料的主要类型。然而,金属配合物受限于金属矿的稀缺性,成本较高,合成路线复杂,不适合工业化大批量生产。因此,为了得到具有高发光效率的器件,仅仅研究金属配合物是不够的,还需开发出其他发光材料。
发明内容
