Abstract

The invention provides a fluorene-containing organic compound and an organic light-emitting device thereof, and relates to the technical field of organic photoelectric materials. In the present invention, a fluorene-containing organic compound is obtained by connecting substituted or unsubstituted triphenylene, fluorene and its derivatives on the main body of aromatic amines, which has strong hole transport ability, electron blocking ability and good thermal stability. , good film-forming properties, simple synthesis and easy operation, it can be applied in organic light-emitting devices as a cover layer or hole transport layer, which can effectively solve the problems of unbalanced carrier transport and low light extraction rate in organic light-emitting devices, its organic The light emitting device has the advantages of high luminous efficiency and long life.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a fluorene-containing organic compound and an organic light-emitting device thereof. Background technique [0002] In 1987, Tang et al. of Kodak Company invented a sandwich-type organic double-layer thin-film light-emitting device. This breakthrough made people see the huge potential of OLED technology to be practical and commercialized, and set off a research boom of organic light-emitting diodes. Over the past 30 years, OLED technology has achieved rapid development, and has moved from laboratory research to industrial production. [0003] At present, the development of OLED materials has reached a relatively mature stage, and material companies at home and abroad provide hundreds of innovative materials for selection. Among them, hole transport materials, electron transport materials, host materials, fluorescent light emitting materials and phosphoresc...
