Description
技术领域
本发明涉及发光材料领域,具体涉及一种有机发光材料及其制法和有机电致发光器件。
背景技术
电致发光器件(electroluminescence device:EL device)作为自发光型显示器件,它具有可视角度宽、对比度好,以及应答速度快的优点。1987年,柯达(Eastman Kodak)公司首次开发了利用低分子芳香二胺和铝络合物作为发光层材料的有机电致发光器件。有机电致发光器件通常结构是以阳极(anode),阴极(cathode)和两极之间的有机物层组成。有机物层可以由发光层、空穴注入层,空穴传输层,电子阻断层,电子缓冲层,空穴阻断层,电子传输层,电子注入层等形成。其中发光层材料是决定器件发光效率、寿命和性能的最重要的因素。发光层材料包括主体材料及掺杂材料,但有机发光主体材料一般载流子的迁移率都普遍较低,因此采用掺杂技术可以大大地提高有机主体材料的迁移率,降低OLED的驱动电压。所以能否研制出新型结构的掺杂材料,能够使器件的发光效率及寿命提高显得至关重要。
