Embodiment 1

[0055] Embodiment 1: the preparation of compound 9

[0056]

[0057] After adding reactant A-9 (50mmol) and reactant B-9 (55mmol) in 200ml of toluene in the reaction vessel, add Pd under nitrogen atmosphere 2 (dba) 3 (0.56mmol), P(t-Bu) 3 (2.8 mmol), t-BuONa (150 mmol). After the addition, the reaction temperature was slowly raised to 110 °C, and the mixture was stirred for 10 h. Use diatomaceous earth to filter while hot to remove salt and catalyst. After the filtrate is cooled to room temperature, distilled water is added to the filtrate for washing. After liquid separation, the organic phase is retained, and the aqueous phase is extracted with ethyl acetate. The combined organic layers were then dried using magnesium sulfate, and the solvent was removed using a rotary evaporator. Using dichloromethane:petroleum ether at a volume ratio of 1:9 as the eluent, the remaining substance was purified by column chromatography to obtain the final product 9 (21.7 g, yield 78%, ...

Embodiment 2

[0058] Embodiment 2: the preparation of compound 23

[0059]

[0060] step 1:

[0061] After adding chemical formula reactant A-23 (50mmol) and reactant B-23 (55mmol) in 200ml toluene in the reaction vessel, add Pd under nitrogen atmosphere 2 (dba) 3 (0.56mmol), P(t-Bu) 3 (2.8 mmol), t-BuONa (150 mmol). After the addition, the reaction temperature was slowly raised to 110 °C, and the mixture was stirred for 10 h. Use diatomaceous earth to filter while hot to remove salt and catalyst. After the filtrate is cooled to room temperature, distilled water is added to the filtrate for washing. After liquid separation, the organic phase is retained, and the aqueous phase is extracted with ethyl acetate. The combined organic layers were then dried using magnesium sulfate, and the solvent was removed using a rotary evaporator. Using dichloromethane:petroleum ether volume ratio: 9 as eluent, the remaining substance was purified by column chromatography to obtain intermediate C-23 ...

Embodiment 3

[0064] Embodiment 3: the preparation of compound 44

[0065]

[0066] step 1:

[0067] After adding chemical formula reactant A-44 (50mmol) and reactant B-44 (55mmol) in 200ml toluene in the reaction vessel, add Pd under nitrogen atmosphere 2 (dba) 3 (0.56mmol), P(t-Bu) 3 (2.8 mmol), t-BuONa (150 mmol). After the addition, the reaction temperature was slowly raised to 110 °C, and the mixture was stirred for 10 h. Use diatomaceous earth to filter while hot to remove salt and catalyst.

Description

technical field [0001] The invention relates to the technical field of luminescent materials, in particular to an organic electroluminescence compound of benzanthracene derivatives and a preparation method and application thereof. Background technique [0002] An organic electrical element utilizing the organic light emitting phenomenon generally has a structure including an anode, a cathode and an organic layer therebetween. Here, the organic layer is generally formed into a multilayer structure composed of various substances in order to improve the efficiency and stability of organic electrical components, for example, it can be composed of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, etc. And electron injection layer etc. are formed. [0003] Among them, hole-transporting materials usually have low highest occupied molecular orbital (HOMO) values, which tend to reduce the efficiency when using materials with fast ho...
