Abstract

The invention provides a fluorene-containing organic compound and an organic light emitting device thereof, which relate to the technical field of organic photoelectric materials. The fluorene-containing organic compound is obtained by connecting a substituted or unsubstituted triphenylene, fluorene and a derivative thereof onto an arylamine main body. The fluorene-containing organic compound hashigh hole transport capacity and electron blocking capacity, good heat stability and good film forming performance, is simple to synthesize and easy to operate, can be applied as a coverage layer or ahole transport layer in an organic light emitting device, and can effectively solve the problems in the organic light emitting device that a charge carrier is imbalanced in transportation and low inlight emitting rate, and an organic light emitting device of the fluorene-containing organic compound has the advantages of high light emitting efficiency and long service 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...
