Embodiment 1

[0050] Embodiment 1, preparation organic optoelectronic material

Embodiment 1-1

[0051] The preparation of embodiment 1-1 intermediate A-1

[0052] Under nitrogen protection, dissolve N-phenylcarbazole (48.6g, 0.2mol) in 500mL DMF (N,N-dimethylformamide) in a 1L three-necked flask, and slowly NBS (N-bromosuccinimide, 78.3 g, 0.44 mol) was added as a solid, and the addition was completed after 0.5 h. The reaction system was kept and stirred at 20-25° C. for 24 hours. After the reaction was completed, an aqueous solution of sodium sulfite (500 mL, 0.05 mol / L) was added to the reaction system, the reaction was quenched, and the filter cake was obtained by suction filtration. After washing with deionized water, crystallization was carried out with toluene or absolute ethanol to obtain a white solid. That is intermediate C01-a, the yield is 90.3%.

Abstract

The invention relates to an organic photoelectric material with a carbazole and iminostilbene structure and application of the organic photoelectric material. A compound structural formula of the organic photoelectric material is as shown in the specification, wherein Ar1 is selected from one of phenyl, phenylalkyl with carbon number being 7-14, polycyclic conjugate aryl with carbon number being 10-60 and aromatic heterocyclic radical containing at least one of N, S and O. The organic photoelectric material which is an OLED (organic light emitting device) material is high in thermal stability and excellent in hole transport capacity and can serve as a hole transport layer of an organic light emitting device to remarkably improve efficiency of the device.

Description

technical field [0001] The invention relates to the field of organic photoelectric materials, in particular to an organic photoelectric material containing carbazole and iminostilbene structures and applications thereof. Background technique [0002] The research on organic electroluminescent devices (OLED light-emitting devices) began in the 1930s. In 1936, Destriau dispersed organic fluorescent compounds in polymers to make thin films, and obtained the earliest electroluminescent devices. However, this Due to the thick film and high turn-on voltage of the device, it did not attract everyone's attention at that time; but in 1982, P.S.Vincett et al. prepared a 0.6 μm thick anthracene film by vacuum deposition, which reduced the driving voltage of the device to below 30V. , which began to attract people's attention; in 1987, it was a milestone year for organic electroluminescent devices. diphenyl-N,N,-bis(3-methylphenyl)-1,1,biphenyl-4,4,diamine(TPD) as hole transport layer,...
