Description
技术领域
本发明属于有机电致发光材料领域,具体涉及螺芴衍生物类胺化合物和包含其的有机电致发光器件。
背景技术
目前,三芳胺或咔唑广泛地用作有机电致发光器件(OLED)的空穴传输材料,常见的空穴传输材料包含1个或者2个三芳胺,含有3个三芳胺或者咔唑的化合物很少用来作为空穴传输材料,主要是由于包含3个三芳胺的前线轨道能级太浅。基于此,本发明从分子结构设计出发,首次尝试并提出一种螺芴衍生物类胺化合物,具体如下所述。
发明内容
本发明提供了螺芴衍生物类胺化合物,具有如化学式1所示的化学结构:
[化学式1]
在化学式1中,Y选自[式a]或/>[式b];
R1–R10各自独立选自氢、取代或未取代的碳原子数为1–20的烷基或烷氧基、取代或未取代的成环碳原子数为6–30的芳基、取代或未取代的成环碳原子数为5–30的杂芳基、或者与相邻基团结合形成取代或未取代的环;
a–d各自独立选自0–4的整数;
L为不存在或亚苯基;
X1和X2独立选自单键、O、S、-NR-或-CRR’-。
与现有技术相比,本发明的有益效果在于:本发明采用9,9-螺芴衍生物上连接3个三芳胺,分子结构的空间位阻较大,其能级合适作为OLED的空穴传输材料。同时该化合物具有三个胺单元即三个可能的空穴传输位点,具有较好的空穴迁移率和空穴传输能力,加上电子在整个分子上分布较为发散,分子结构比较稳定,作为空穴传输材料可以降低OLED的功耗,延长器件的使用寿命。
附图说明

图2是实施例中顶部发光有机电致发光器件的结构示意图。

按照如图1所示的结构制作单蓝色底部发光非串联有机电致发光器件,制备工艺为:在玻璃材质的基底101上,形成透明阳极ITO膜层,膜厚150nm,得到第一电极102作为阳极,之后蒸镀与化合物/>的混合材料作为空穴注入层103,混合比例为3:97(质量比),之后蒸镀100nm厚度的本发明化合物A1,得到第一层空穴传输层104,然后蒸镀20nm厚度化合物/>得到第二层空穴传输层105,然后以95:5的蒸镀速率蒸镀/>与/>30nm,制作蓝光发光单元106,然后蒸镀10nm/>形成电子阻挡层107,然后蒸镀/>与/>混合比例为4:6(质量比)形成厚度30nm的空穴传输层108,之后蒸镀形成厚度1nm的金属镱,再形成100nm的金属银作为双层镱/银金属作为第二电极109。
器件实施例2至8中分别采用上述化合物A10、A14、A20、A25、A28、A33、A41以及对比例1和2中分别采用化合物和/>替代器件实施例1中化合物A1作为空穴传输层104来制作蓝光有机电致发光器件,得到的有机电致发光器件进行发光效率性能测试,如表1所示。
表1
从表1可以看出,本发明中螺芴衍生物类胺化合物作为蓝色底部发光非串联有机电致发光器件的空穴传输层材料,得到的器件驱动电压低、发光效率高且使用寿命长。
此外,本发明中螺芴衍生物类胺化合物还可以作为图1所示的顶部发光器件的空穴传输层105,或者作为图2所示的底部发光器件的空穴传输层104和/或105,或者作为串联有机电致发光器件的多层空穴传输层材料,得到的器件效果同样显著。
另外,本发明还提供包含上述任一有机电致发光器件的显示装置。
