Description
技术领域
本发明涉及一种有机金属配合物发光材料,尤其是用于OLED发光器件中,在发光层中起光子发射作用的掺杂剂。
背景技术
OLED(Organic Light-Emitting Diode,有机发光二极管)技术自1987年由柯达公司的邓青云博士首次发表相关工作(Organic electroluminescent diodes.AppliedPhysics Letters.1987,51卷,12期,913页)以来,到现在已经经过了30年的蓬勃发展。近5年OLED技术由于其独特性吸引了大量工业界的关注和投资。在显示领域,相比目前主流的LCD(Liquid Crystal Display,液晶显示)显示技术,OLED显示具有高亮度、高对比度、高分辨率、超薄显示、柔性显示的巨大优势;在照明领域,OLED照明具有高显色指数(CRI,ColorRendering Index)、平面光源、柔性光源等巨大优势。OLED发光技术目前面临最大的劣势,就是成本高,寿命短。
OLED器件由很多功能层构成。其中发光层中,发射绿光和红光的掺杂剂效果最好、应用最广的是磷光发光材料。目前常用的磷光发光材料有两种,一种是含有金属铱(Ir)的有机金属配合物,另一种是含有金属(Pt)的有机金属配合物。红光、绿光金属Ir配合物均有性能非常好的材料。
由于金属铱具有6个配位点,所以含有Ir的有机金属配合物具有正八面体的立体结构。用于合成Ir配合物的有机化合物配体大多数只有两个配位点,故而一个分子里需要有3个相同或不同的有机配体。绝大多数配体结构不对称,所以合成金属铱(Ir)的有机金属配合物的时候,会得到分子量完全一致、发光性能完全不同的两种构型,称为经式(mer)构型和面式(fac)构型。面式构型相对经式构型,具有更高的发光效率,但是将其分离出来具有很高的成本,尤其是工业生产过程中。为了解决这个问题,可以引入辅助配体(US6830828),也可以通过紫外线照射提高分子经式向面式构型的转化率。
金属铂具有4个配位点,可以通过设计四齿配体形成唯一构型,可以完全避免异构体的形成。Mark等人用卟啉作为配体,可以形成具有唯一构型的Pt有机金属配合物(US6303238),但是发光效果不好,器件的量子效率只有不到1%;Chi等设计了一系列具有席夫碱结构的四齿配体(US20050233167),其发光覆盖了绿光到红光区的波段。但目前仍存在红光分子的荧光量子效率低(40%左右)的问题。

具有结构(II)的化学结构的有机金属配合物,为了实现红光发射,需要含有席夫碱的基本结构(即式中N原子与相邻原子形成的结构)。在背景中提到,具有席夫碱结构的Pt有机金属配合物的红光发射存在荧光量子效率偏低的问题。为了提高分子的荧光量子效率,有两个主要方法:1、引入强σ-给体配体;2、增强分子刚性,减少分子激发态下构型的扭曲(Chi,Chem.sci.,2016,7,1653)。在不改变分子的电子结构的情况下,扩大式II中D,E,F环的共轭面积,可以有效地提高分子的刚性。如此设计的分子在激发态下的振动便会受限,电子跃迁的模式会减少,这样可以直接提高分子的荧光量子效率。
在增强了核心的荧光量子效率的前提下,再通过向D、E、F环引入防聚集基团,可以抑制高激子浓度下,三线态激子的淬灭。如此便可以在保证高工作电流下的电流效率不发生明显变化的情况下,增加掺杂的浓度,进一步提高器件的工作效率。
如式(II)所示的具体实例,包括但不限于以下结构:
采用具有结构(II)的有机金属配合物,可制造热沉积和溶液处理的OLED。
包括含有一种或多种如权利要求1中所述的用于发光二极管的发光材料的有机发光器件。
其中通过热沉积在该器件中以层形式施加该用于发光二极管的发光材料。

其中通过喷墨打印在该器件中以层形式施加该用于发光二极管的发光材料。
上述有机发光器件,其中在对层施加电流时该器件发射单色-红色。
本发明中的有机金属配合物具有高荧光量子效率,良好的热稳定性及低淬灭常数,可以制造高效率低效率滚降的红光OLED。
