有机发光化合物及其制备方法和含该化合物的有机电致发光器件
相关申请的交叉引用
本申请要求于2018年10月11日提交中国国家知识产权局的申请号为201811180993.X、名称为“有机发光化合物及其制备方法和含该化合物的有机电致发光器件”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及有机发光材料技术领域,具体涉及一种有机发光化合物及其制备方法和含该化合物的有机电致发光器件。
背景技术
有机电致发光装置(organic electroluminescent device),也称作有机发光二极管(organic light-emitting diode;OLED),是以有机层作为主动层的一种发光二极管(LED)。由于有机电致发光装置具有低电压操作、高亮度、重量轻、广视角、以及高对比值等优点,近年来已渐渐使用于平面面板显示器(flat panel display)上。与液晶显示器不同,有机电致发光显示器所包含的有机发光二极管象素数组是具有自发光的特性,因此不需外加背光源。一般而言,有机发光二极管组件包括一对电极,以及在电极之间的一有机发光介质层。在外加电场的作用下,电子和空穴分别从阴极和阳极向夹在电极之间的有机发光介质层注入,注入的电子和空穴分别从电子传输层和空穴传输层向发光层迁移,电子和空穴在有机发光介质层中相遇产生激子(excitons),激子在有机发光介质层中不断地作自由扩散运动,并以辐射或无辐射的方式失活,当激子由激发态以辐射跃迁的方式回到基态,就可以观察到电致发光现象,发射光的颜色由激发态到基态的能级差所决定。
依据空穴和电子的自旋态(spin state),由空穴和电子的再结合而产生的激子可具有三重态(triplet)或单重态(singlet)的自旋态。由单重态激子(singlet exciton)所产生的发光为荧光(fluorescence),而由三重态激子(triplet exciton)所产生的发光为磷光(phosphorescence)。磷光的发光效率是荧光的三倍。因此,发展高效率的磷光材料以增进有机发光二极管组件的发光效率是非常重要的。
发明内容
