Embodiment 1

[0104] Embodiment 1. Preparation of organic optoelectronic materials

Embodiment 1

[0105] Example 1 Preparation of aforementioned compound 1

[0106] (1) Preparation of compound 1-a:

[0107]

[0108] At -15°C and under the protection of nitrogen, 23.1g of 2-bromo-4-hydroxybenzoic acid methyl ester (100.0mmol) and 121.4g (120mmol) of triethylamine were dispersed in 200g of dichloroethane, then drop Add 31.0 g of trifluoromethanesulfonic anhydride (110 mmol), after the dropwise addition, keep warm for 2.0 hours, then slowly warm up the reaction system to room temperature, then pour the above system into 200 g of water, stir and react for 30 min, the system is layered, and water is used to carry out the reaction. After washing, the organic phase was finally desolvated under reduced pressure until there was no fraction, and 36.1 g of compound 1-a was obtained without further purification.

[0109] (2) Preparation of compound 1-b:

[0110]

[0111] Get the 36.1g compound 1-a (100.0mmol), 20.7g potassium carbonate (150mmol), 80g water, 11.0g phenylboron...

Embodiment 2

[0133] Example 2 Preparation of aforementioned compound 8

[0134] (1) Preparation of compound 8-a:

[0135]

[0136] Take the 36.1g compound 1-a (100.0mmol), 20.7g potassium carbonate (150mmol), 80g water, 22.3g phenylboronic acid (90mmol) and 300g toluene obtained in step (1), under the protection of nitrogen, add catalyst 0.9 g Pd(PPh 3 ) 4 (0.75mmol), then heated to reflux, while adopting thin-layer chromatography (TLC) to track the reaction process, after about 6.0 hours of reaction, after being down to room temperature, the system was layered, and then after washing with water, the organic phase was decompressed and decompressed. Solvent until there is no fraction, and then use petroleum ether ethyl acetate mixture to carry out column chromatography purification to the residue, wherein the volume ratio of petroleum ether and ethyl acetate is petroleum ether:ethyl acetate=25:1, to obtain 22.5g of compound 8- a, The yield is 59.84%.

Abstract

The present invention relates to a spiro ring organic photoelectric material and a preparation method thereof, and an organic electroluminescent device containing the spiro ring organic photoelectric material. According to the present invention, the provided organic electroluminescent device contains the spiro ring organic photoelectric material, such that the quantum efficiency, the current efficiency, the power efficiency and the brightness of the organic electroluminescent device can be substantially improved while the driving voltage is substantially reduced so as to significantly improve the service life of the organic electroluminescent device.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a spiro-ring organic optoelectronic material, its preparation method and its application. Background technique [0002] The origin of organic light emitting diode (OLED) can be traced back to the 1960s. Pope et al. used an anthracene single crystal to apply DC voltage to make it emit light, but due to the high driving voltage (100V) Moreover, the luminous brightness and efficiency are relatively low, which has not attracted too much attention. With the continuous improvement of technology. In 1987, C.W.Tang et al. of Kodak Company used 8-hydroxyquinoline aluminum (Alq3) as the luminescent material, and used the method of vacuum evaporation to make an OLED with a double-layer sandwich structure. The voltage is only a few volts, and the brightness can reach up to 1000cd / m 2 , thus marking an important step toward practical use of OLEDs, thus becoming an important mileston...
