Abstract

The invention provides an organic semiconductor material, which is characterized in that indolocarbazole heteroaromatic rings are constructed to realize high heat resistance, high charge transmission performance and good processability. An organic light emitting diode applying the organic semiconductor material has the characteristics of high efficiency, low voltage and long work life.

Description

[0001] Technical field: [0002] The invention relates to an organic semiconductor compound and the application of the prepared organic electroluminescent device. A series of organic semiconductor compounds with asymmetric structure and organic semiconductor compounds with crosslinking groups can be obtained by using an indolocarbazole as a structural element and a well-developed organic donating or accepting unit, which can be applied to organic light-emitting OLED devices , improve the charge injection, solubility and processability of luminescent materials, which is beneficial to the large-scale production of OLED display devices. [0003] Background technique: [0004] Organic semiconductor materials are new types of optoelectronic materials, and their large-scale research originated in 1977 by Shirakawa Hideki, A. Heeger and A. McDiamid who jointly discovered doped polyacetylene with conductivity up to copper level. Subsequently, in 1987, C.Tang of Kodak Company invented ...
