Description
技术领域
本发明涉及有机电致发光材料领域，具体涉及一种含有喹喔啉基团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OLED材料中，由于大多有机电致发光材料传输空穴的速度要比传输电子的速度快，容易造成发光层的电子和空穴数量不平衡，这样器件的效率就比较低。三(8-羟基喹啉)铝(Alq3)自发明以来，已经被广泛地研究，但是作为电子传输材料它的电子迁移率还是很低，并且自身会降解的内在特性，在以之为电子传输层的器件中，会出现电压下降的情况，同时，由于较低的电子迁移率，使得大量的空穴进入到Alq3层中，过量的空穴以非发光的形式辐射能量，并且在作为电子传输材料时，由于它发绿光的特性，在应用上受到了限制。因此，发展稳定并且具有较大电子迁移率的电子传输材料，对有机电致发光器件的广泛使用具有重大的价值。
