Paragraph 0129-0131; 0132; 0136, (2021/11/10)
The present invention relates to an organic compound and an organic electroluminescent device and an electronic device using the same, wherein the organic compound has a structure formed by combining an indole carbazole-based planar conjugated group in a fused manner and a dibenzofuran substituted with an aryl group. The structure has higher hole mobility and higher energy transfer efficiency, and is suitable for being used as a light-emitting host material in an organic electroluminescent device. When the organic compound is used as a light emitting host material in an organic electroluminescent device, the light emitting efficiency and the service life of the device can be effectively improved, and the working voltage is reduced.
