Embodiment Construction

[0017] Please refer to the following chemical formula I to show the 6H-indole [3,2-b] quinoxaline derivatives of the present invention,

[0018]

[0019] Among them, R 9 It can be selected from an aryl group and a heteroaryl group having one or more substituents. The aryl group is, for example, phenyl, naphthyl, diphenyl, anthryl, pyrenyl, phenanthryl, fluorene or other polyphenyl groups. Heteroaryl is, for example, pyrane, furan, benzofuran, thiophene, benzothiophene, pyridine, quinoline, isoquinoline ( isoquinoline), pyrazine, pyrimidine, pyrrole, pyrazole, imidazole, indole, thiazole, isothiazole, oxazole ( oxazole), isoxazole (isoxazole), benzothiazole (benzothiazole), benzoxazole (benzoxazole), 1,2,4-triazole (1,2,4-triazole), 1,2,3 triazole Azole (1,2,3-triazole), 1,2,3,4-tetraazole (1,2,3,4-tetraazole), phenanthroline or other heterocyclic aromatic groups.

[0020] R 1 to R 8 and R 9 The substituents are independently selected from hydrogen (H), halogen (halog...

Abstract

The invention relates to a 6H-indole[3, 2-b]quinoxaline derivative and an organic light-emitting diode thereof. The 6H-indole[3, 2-b]quinoxaline derivative has a chemical formula (I), wherein R9 can be selected from aryl group with one or more substituent(s) and heteroaryl with one or more substituent(s); and R1 to R8 are provided with substituents. The compound has a 6H-indole[3, 2-b]quinoxaline function group, indole and quinoxaline are combined, and thus the compound has good energy transfer capacity of the indole and good electron injection capacity of the quinoxaline, can be used as a main light-emitting material or a dopant of a light-emitting layer, and can also be used as a hole transmission material, an electron transmission material, a hole blocking material, an electron blocking material, a hole injection material or an electron injection material.

Description

technical field [0001] The invention relates to a compound and its organic light-emitting diode, especially a 6H-indole [3,2-b]quinoxaline derivative and its organic light-emitting diode. Background technique [0002] Organic light-emitting diode (OLED) is a light-emitting element made of organic materials or organic semiconductor materials. The holes are recombined to form excitons, and the excitons undergo energy transfer to emit light, and its color is controlled by the light-emitting material. Organic light-emitting diodes have self-illumination, wide viewing angle (>170°), short response time (~μs), high contrast, high efficiency, power saving, high brightness, low operating voltage (3-10V), lighter and thinner (<2mm) , flexibility and other advantages, so it has attracted much attention in recent years. [0003] Excitons generated by the recombination of holes and electrons may have a spin state of a triplet state or a singlet state. The luminescence generated...
