一种基于双极磷光衍生物的有机发光材料及其有机发光器件
摘要：
本发明提供一种基于双极磷光衍生物的有机发光材料及其有机发光器件，属于有机光电材料技术领域。解决现有技术中有机光电材料发光效率低、使用寿命短等发光性能差的技术问题。本发明以二氢吩嗪基团连接喹唑啉基团为核，使得结构中兼有得电子与失电子基团，从而得到一种新颖的电子与空穴双极传输型材料。与现有技术相比，本发明的基于双极磷光衍生物的有机发光器件，发光效率最高可达19.7cd/A，发光寿命为210h@100mA/cm2，是一种优异的OLED材料。
摘要（英）：

The invention provides a bipolar phosphorescence derivative-based organic light-emitting material and an organic light-emitting device thereof, belongs to the technical field of organic photoelectric materials, and solves the technical problems of low light-emitting efficiency, short service life, low light-emitting performance and the like of an organic photoelectric material in the prior art. A dihydrophenazine group is connected with a quinazoline group to form a core, so that the structure contains an electron group and a betatopic group, and a novel electron and hole bipolar transmission material is obtained. Compared with the prior art, the bipolar phosphorescence derivative-based organic light-emitting device has the advantages that the light-emitting efficiency is up to 19.7 cd/A to the maximum extent, and the light-emitting life is 210h@100mA/cm<2>, so that the bipolar phosphorescence derivative-based organic light-emitting device is an excellent OLED (Organic Light Emitting Diode) material.
