Abstract
Description
technical field
[0001] The invention relates to the technical field of organic electroluminescent diodes, and more specifically relates to a novel organometallic iridium complex, a preparation method thereof and an organic electroluminescent device containing the metal iridium complex. Background technique
[0002] Organic electroluminescence (referred to as OLED) and related research As early as 1963, Pope et al. first discovered the electroluminescence phenomenon of organic compound single crystal anthracene. In 1987, Kodak Corporation of the United States made an amorphous device by evaporating organic small molecules, which reduced the driving voltage to within 20V. OLED is a hole and electron double-injection light-emitting device, which directly converts electrical energy into light energy of organic semiconductor material molecules. Compared with traditional CRT, LCD, PDP and other display devices, OLED takes into account all the advantages of existing displays, and ...
