Abstract

The invention relates to a high luminance, high efficiency indole 3,2-b carbazole derivatives organic electroluminescenct material, belonging to the organic electroluminescent material technical field. The general structural formula of the indole 3,2-b carbazole derivatives organic electroluminescent compound is in the picture; in which, R3, R7 is alkyl or the substitute aryl, R1, R2 or R4-R6, R8 is hydrogen atom, benzene, naphthaline, anthracene, fluorine, carbazole, triarylated amine, thiophene, pyridine, pyran, quinoline, pyrrole, furan or imidazole. The compound of the invention has high fluorescence in both solution and solid film and has high film forming ability, thermal stability and photostability.

Description

technical field [0001] The invention relates to a high-brightness, high-efficiency indole[3,2-b]carbazole derivative organic electroluminescent material, which belongs to the technical field of organic electroluminescent materials. Background technique [0002] Since the existing display technology cannot meet people's higher and higher requirements for information display equipment, people are constantly looking for newer and more efficient luminescent materials, in-depth research on their luminescence mechanism, and preparation of display devices with higher performance and lower cost. Organic light-emitting diodes (OLED) emerged as a new generation of flat panel display technology. OLED has a series of advantages such as self-illumination, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Compared with liquid crystal displays, OLED does not require a backlight, has a large viewing angle, low power, fast response, and low cost. Therefore, organic ele...
