Description

一种化合物及有机电致发光器件
技术领域
本发明涉及有机电致发光技术领域,具体涉及一种化合物及有机电致发光器件。
背景技术
有机电致发光器件(Organic Light-emitting Devices, OLED)是利用如下原理的自发性发光器件:当施加电场时,荧光物质通过正极注入的空穴和负极注入的电子的重新结合而发光。这种自发光器件,具有电压低、亮度高、视角宽、响应快、温度适应性好等特性,并且超薄,能制作在柔性面板上等优点,广泛应用于手机、平板电脑、电视、照明等领域。
OLED作为一种利用多层有机薄膜结构产生电致发光的器件,它很容易制作,而且只需要低的驱动电压,这些主要的特征使得OLED在满足平面显示器的应用上显得非常突出。OLED显示屏比LCD更轻薄、亮度高、功耗低、响应快、清晰度高、柔性好、发光效率高,能满足消费者对显示技术的新需求。全球越来越多的显示器厂家纷纷投入研发,大大的推动了OLED的产业化进程。
对于有机电致发光器件提高性能的研究,目前主要集中在如何降低器件的驱动电压、提高器件的发光效率、提高器件的使用寿命等方向。为了实现有机电致发光器件性能的不断提升,不但需要有机电致发光器件的结构和制作工艺的创新,更需要有机电致光电功能材料的不断研究和创新,创制出更高性能的有机电致功能材料。
目前,就当前有机电致发光产业的实际需求而言,有机电致发光材料的发展还远远不够,落后于面板制造企业的要求,需要继续提高发光器件的发光效率及寿命,推进OLED材料的国产化。

一种含有上述有机电致发光器件的电子显示设备。
一种含有上述有机电致发光器件的OLED照明设备。
本发明所述室温均为25±5℃。
本发明的有益效果:
本发明设计了一款应用于OLED有机电致发光材料,本发明的有机电致发光化合物是以富电子基团-咔唑及咔唑衍生物、吸电子基团-三嗪、及增加寿命的二苯并呋喃及其衍生物以特定的方式连接而成的化合物;
一方面,在式1所示基团中将二苯并呋喃及其衍生物的4-号位与三嗪基团连接,该连接方式有三个好处:1、将二苯并呋喃的4-号活泼位置保护起来,增加该类化合物的热稳定性及化学稳定性;2、该种连接方式能够增加化合物的扭矩,提高该类化合物的三线态能级,避免能量由掺杂材料向主体材料的反向传递;3、该种连接方式在增加化合物扭矩的同时,增加了材料的溶解性,增加了该类材料的量产性、降低了制备成本。
另一方面,式1中咔唑及其衍生物与三嗪基团直接连接即D-A结构,而非通过苯环等方式进行桥连即D-π-A的结构,该种连接方式能够导致该类化合物HOMO、LUMO的分离,进而减小该类材料的单线态与三线态之间的能极差即较小∆Est的值。∆Est数值的较小,有利于该类化合物的三线态向单线态的反向系间窜跃,使该类材料具备了成为TADF材料的可能性。进而提高了器件的发光效率及寿命。
经过器件验证,使用本发明设计的化合物与相应的P-type材料搭配制备的有机电致发光器件,其发光效率及寿命均有显著的提高。
