Description

[0001] Technical field:

[0002] The invention relates to a light-emitting organic metal iridium complex and an organic electroluminescent device prepared therefrom. The use of an improved light-emitting metal iridium complex in the light-emitting layer can be applied to organic light-emitting OLED devices, and the charge injection, solubility and processability of light-emitting materials can be improved, which is beneficial to the large-scale production of OLED display devices.

[0003] Background technique:

[0004] Organic semiconductor materials are new optoelectronic materials, and its large-scale research originated in 1977 by 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.Friend and A.Holmes of Cambridge University invented the polymer light-emitting diode P-OLED, and in 1...
