Description

technical field [0001] The invention relates to the field of organic electroluminescence, in particular to a quinone organic compound, a mixture, a composition and an organic electronic device. Background technique [0002] In flat panel display and lighting applications, organic light-emitting diodes (OLEDs) have become the most promising due to their advantages of low cost, light weight, low operating voltage, high brightness, color tunability, wide viewing angle, easy assembly, and low energy consumption. potential display technology. In order to improve the luminous efficiency of OLEDs, various fluorescent and phosphorescent luminescent material systems have been developed. In order to improve the recombination efficiency of the injected holes and electrons, further improvements in the structure and materials of the organic light emitting diode are required. [0003] At present, Merck uses aromatic diamine derivatives or aromatic fused ring diamine derivatives as hole ...
