Description
技术领域
本发明涉及有机电致发光材料领域,具体涉及一种基于酚嗪和咔唑的有机电致发光化合物及其有机电致发光器件,属于有机电致发光器件显示技术领域。
背景技术
有机电致发光器件(OLEDs)为在两个金属电极之间通过旋涂或者真空蒸镀沉积一层有机材料制备而成的器件,一个经典的三层有机电致发光器件包含空穴传输层、发光层和电子传输层。由阳极产生的空穴经空穴传输层跟由阴极产生的电子经电子传输层结合在发光层形成激子,而后发光。有机电致发光器件可以根据需要通过改变发光层的材料来调节发射各种需要的光。
有机电致发光器件作为一种新型的显示技术,具有自发光、宽视角、低能耗、效率高、薄、色彩丰富、响应速度快、适用温度范围广、低驱动电压、可制作柔性可弯曲与透明的显示面板以及环境友好等独特优点,可以应用在平板显示器和新一代照明上,也可以作为LCD的背光源。
自从20世纪80年代底发明以来,有机电致发光器件已经在产业上有所应用,比如作为相机和手机等屏幕,但是目前的OLED器件由于效率低,使用寿命短等因素制约其更广泛的应用,特别是大屏幕显示器,因此需要提高器件的效率。而制约其中的一个重要因素就是有机电致发光器件中的有机电致发光材料的性能。另外由于OLED器件在施加电压运行的时候,会产生焦耳热,使得有机材料容易发生结晶,影响了器件的寿命和效率,因此,也需要开发稳定高效的有机电致发光材料。
在有机电致发光器件中,空穴传输材料和注入材料的引入,可以有效地降低正电荷从正极传输到发光层的能力,提高器件的效率和热稳定。传统的空穴注入材料,如copperphthalocyanine(CuPc),降解慢,制备耗能高,不利于环境保护,而且其会吸收光,影响器件的效率。NPB等原始的空穴传输材料,热稳定性比较差,也很大程度影响器件寿命。因而,需要开发高效稳定的有机电致发光材料。
