Abstract

An organic semiconductor material is characterized by indolocarbazole derivative heteroaromatic ring as the molecule structure thereof, so that the organic semiconductor material has the properties of high heat resistance, stability and high charge transmission and processing performance. Organic light-emitting diode made of the organic semiconductor material has the advantages of high efficiency, low voltage and long service lifetime.

Description

technical field [0001] The invention relates to an organic semiconductor compound and the application of the prepared organic electroluminescent device. Using a modified indolocarbazole and its derivatives containing electrophilic pyridine as the main structural element to obtain a series of asymmetrically improved organic semiconductor compounds, which can be applied to organic light-emitting OLED devices and improve the charge injection and solubility of light-emitting materials , processability, which is conducive to the large-scale production of OLED display devices. Background technique [0002] Organic semiconductor materials are new types of optoelectronic materials, and their large-scale research originated in 1977 when Hideki Shirakawa, A. Heeger and A. McDiamid jointly discovered doped polyacetylene with conductivity up to copper level. Subsequently, in 1987, C. Tang of Kodak Company invented the organic small molecule light-emitting diode (OLED), and in 1990, R. ...
