Synthetic example 1

[0095] Synthesis of V9

[0096]

[0097] Intermediate 1-1:

[0098] At room temperature, add raw material A (20g, 83.36mmol), raw material B (59.78g, 175.05mmol), Pd132 (19.48g, 25.01mmol), sodium tert-butoxide (16.02g, 166.72mmol), di Toluene (600ml) was used as a solvent, nitrogen was replaced three times, the temperature was raised to 120°C for 12 hours, then heating was stopped, filtered and evaporated to dryness, purified by column chromatography (petroleum ether:dichloromethane=10:1), and 51.0g of the product was obtained. Molecular mass determined by mass spectrometry: 804.6 (theoretical: 804.4).

[0099] Material V9:

[0100] Intermediate 1-1 (51g, 63.35mmol) was dissolved in 500ml of xylene, and n-butyllithium (76.0ml, 190.05mmol) was slowly added dropwise at -40°C. Heat and activate at ℃ for 2 hours, then cool down to -40℃, add BBr slowly 3 (45.03g, 158.4mmol), and DIEA (37.2g, 253.4mmol), heated at 110°C for 10h after returning to room temperature, then stopp...

Description

technical field [0001] The invention relates to the technical field of organic luminescent materials, in particular to an organic compound and its application, and an organic electroluminescent device containing the same. Background technique [0002] In recent years, optoelectronic devices based on organic materials have become increasingly popular. The inherent flexibility of organic materials makes them very suitable for manufacturing on flexible substrates. They can design and produce beautiful and cool optoelectronic products according to requirements, and obtain incomparable advantages over inorganic materials. Examples of such organic optoelectronic devices include organic light emitting diodes (OLEDs), organic field effect transistors, organic photovoltaic cells, organic sensors, and the like. Among them, OLED is developing rapidly, and has achieved commercial success in the field of information display. OLED can provide high-saturation red, green, and blue colors,...
