6H-吲哚并[2,3-b]喹喔啉衍生物和使用其的有机发光二极管

6H-indolo[2,3-b]quinoxaline derivatives and organic light emitting diode using the same
Abstract:
A 6H-indolo[2,3-b]quinoxaline derivative has a structure of formula (I). R9 is a member selected from the group consisted of an aryl group having one or more substituents and a heteroaryl group having one or more substituents, and R1 to R8 are substituents. The 6H-indolo[2,3-b]quinoxaline derivative of the present invention incorporates an indole and a quinoxaline group therefore inherits good energy transfer ability from indole and good electron-injection ability from quinoxaline. The compound of the present invention may function as a host material or a dopant in the light-emitting layer. In addition, the compound of the present invention may function as hole transport material, electron transport material, hole blocking material, electron blocking material, hole injecting material or electron injecting material.
Abstract(Chinese):

6H-吲哚并[2,3-b]喹喔啉衍生物具有式（I）的结构。 R9是选自具有一个或多个取代基的芳基和具有一个或多个取代基的杂芳基的基团，R 1 -R 8是取代基。 因此，本发明的6H-吲哚并[2,3-b]喹喔啉衍生物掺入吲哚和喹喔啉基因而具有良好的吲哚能量转移能力和来自喹喔啉的良好的电子注入能力。 本发明的化合物可以在发光层中起主体材料或掺杂剂的作用。 此外，本发明的化合物可以用作空穴传输材料，电子传输材料，空穴阻挡材料，电子阻挡材料，空穴注入材料或电子注入材料。
