[0159] Synthesis of Intermediates

[0160]

[0161] To a dry and nitrogen purged round bottom flask was added 1-bromo-2-iodo-3-chlorobenzene (50.0 g, 157.5 mmol), phenylboronic acid (19.2 g, 157.5 mmol), tetrakis(triphenylphosphine) Palladium (9.1 g, 7.8 mmol), tetrabutylammonium bromide (2.5 g, 7.8 mmol), potassium carbonate (65.2 g, 472.6 mmol), toluene (400 mL), ethanol (200 mL), deionized water (100 mL), The temperature was raised to 75°C under stirring and kept for 8 h; then the reaction mixture was cooled to room temperature, deionized water (200 mL) was added, stirred for 15 minutes, the organic phase was separated, and anhydrous magnesium sulfate was added to dry, and the solvent was removed under reduced pressure; the obtained The crude product was purified by silica gel column chromatography using dichloromethane / n-heptane (1:3) as mobile phase to obtain intermediate SM-D (35.8 g, 85% yield).

[0215] Example 1: Green Organic Electroluminescent Device

[0216] Anodes were prepared by the following process: ITO thickness was The substrate (manufactured by Corning) was cut into a size of 40mm × 40mm × 0.7mm, and a photolithography process was used to prepare it into an experimental substrate with cathode, anode and insulating layer patterns, using ultraviolet ozone and O 2 :N 2 A plasma surface treatment was performed to increase the work function of the anode (experimental substrate) and to remove scum.

[0217] Vacuum evaporation of F4-TCNQ on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and NPB was evaporated on the hole injection layer to form a thickness of the hole transport layer.

[0218] Compound 1 was vacuum evaporated on the hole transport layer to form a thickness of electron blocking layer.

[0219] On the electron blocking layer, GH-n1:GH-n2:Ir(ppy) 3 Co-evaporation was carried out in the ratio of 50...

Embodiment 2- Embodiment 40

[0223] In forming the electron blocking layer, the compound shown in Table 12 was substituted for Compound 1 in Example 1, and an organic electroluminescent device was fabricated by the same method as in Example 1.

Description

technical field [0001] The present application belongs to the technical field of organic materials, and specifically provides a nitrogen-containing compound and electronic components and electronic devices using the same. Background technique [0002] With the development of electronic technology and the progress of material science, the application scope of electronic components for realizing electroluminescence or photoelectric conversion is more and more extensive. Such electronic components usually include oppositely disposed cathodes and anodes, and functional layers disposed between the cathodes and the anodes. The functional layer is composed of multiple organic or inorganic film layers, and generally includes an energy conversion layer, a hole transport layer between the energy conversion layer and the anode, and an electron transport layer between the energy conversion layer and the cathode. [0003] Taking an organic electroluminescence device as an example, it ge...
