Abstract

The invention belongs to the field of photoelectric materials, and particularly relates to an organic compound and an organic electroluminescent device containing the same. According to the organic compound provided by the invention, carbazole, a dibenzo six-membered ring and an aza-carbazole group are bonded with phenyl at a fluorene core C9 site to form a main body, and the phenyl is further modified by an electron / hole transport group to form the organic compound. The compound is of a star-shaped structure, vacuum evaporation film forming is good, electron / hole transmission is balanced, and the photoelectric property and the service life of an organic light-emitting device prepared from the compound are remarkably improved.

Description

technical field [0001] The invention belongs to the field of optoelectronic materials, in particular, the invention relates to an organic compound and an organic electroluminescent device comprising the same. Background technique [0002] Organic electroluminescent (OLED) devices have the characteristics of self-luminescence, high efficiency and energy saving, and have been applied in new display fields such as smart phones and tablet computers. It is very extensive, but compared with the actual industry demand, the performance of OLED devices needs to be further improved. [0003] The OLED device structure is similar to a sandwich, including electrodes on both sides and an organic layer in the middle. The organic layer in the middle can be further divided into a hole / electron injection layer, a hole / electron transport layer, a light-emitting layer, and a hole / electron blocking layer. Layers, etc., various functional materials are stacked together to realize the electrolumi...
