Paragraph 0149-0152, (2019/10/08)
The present invention relates to an organic compound having a dibenzophenazine moiety connected to a hetero-aromatic moiety via a linker. The organic compound has a hetero-aromatic moiety with desirable n-type properties and thus minimizes exciton quenching due to an interaction between a triplet exciton of a dopant and a hole-polaron formed in proximity. Accordingly, the organic compound may prevent the service lifetime of a light-emitting diode device from decreasing due to electro oxidation and photo oxidation. Further, the organic compound due to a dibenzophenazine moiety with a stable structure, has excellent thermal stability; and does not suffer a decrease in energy band gap and triplet excited state energy level (T_1), thereby improving luminance efficiency. Thus, the organic compound may be used in combination with, for example, a delayed fluorescence dopant emitting a blue light, to be used as a host of a light-emitting material layer. The organic compound may be applied to an organic light-emitting diode, an organic light-emitting device, and the like, to improve luminance efficiency and device lifetime thereof.COPYRIGHT KIPO 2019
