Embodiment

[0227] In this specification, all temperatures are in degrees Celsius unless otherwise stated.

[0228] In this specification, unless otherwise stated, all reagents used in the examples were purchased from commercial suppliers and used without further purification.

[0229] Anhydrous tetrahydrofuran, dioxane, and toluene ethyl ether used in the examples of this specification were all obtained by reflux drying of metal sodium; anhydrous dichloromethane and chloroform were obtained by reflux drying of calcium hydride; ethyl acetate, petroleum ether, n-hexane Alkanes, N,N-dimethylacetamide and N,N-dimethylformamide were dried over anhydrous sodium sulfate before use.

[0230] In the examples of this specification, unless otherwise stated, the reaction is generally carried out under nitrogen or argon positive pressure or on an anhydrous solvent with a drying tube, a suitable rubber stopper on the reaction bottle, and the substrate is injected into the reaction via a syringe. , gl...

[0231] Preparation Example 1: Synthesis of Compound 15

[0232] 1) Synthesis of Intermediate-1

[0233] Add 100g (that is, 373.5mmol) of 2-chloro-4,6-diphenyl-1,3,5-triazine into a three-necked flask filled with 1L tetrahydrofuran (THF), and add 25.12g of it dropwise at -78°C (i.e. 392.20mmol) n-butyllithium (n-Buli), after the dropwise addition, keep warm for 1h, then add 40.85g (i.e. 1120.5mmol) trimethyl borate dropwise, continue to keep warm for 1h, then warm up to room temperature and stir overnight. Add hydrochloric acid (2 mol / L) to adjust the pH to neutral, obtain a white crude product by filtration, and slurry with n-heptane to obtain 72.1 g of white solid Intermediate-1 (yield 70%).

[0235] 2) Synthesis of Intermediate 2

[0236]

[0237] 2.1) Synthesis of intermediate 2-1

[0238] 100g (ie 315.1mmol) of 2-bromo-4-chloro-1-iodobenzene, 49.27g (ie 315.1mmol) p-chlorophenylboronic acid, 18.21g (ie 15.7mmol) tetrakis (triphenylphosphine) palladium (Pd...

[0250] Preparation Example 2: Synthesis of Compound 17

[0251] Compound 17 was synthesized using the same method as in Preparation 1 (yield 76%, LC-MS (ESI, pos.ion): m / z=749.3 ([M+H] + )), the difference is that the following raw materials 1 and raw materials 2 are used to replace 2-bromo-4-chloro-1-iodobenzene and p-chlorophenylboronic acid used to prepare intermediate 2 in Preparation 1, thus obtaining the following intermediate Body 3-1, Intermediate 3-2 and Intermediate 3.

Abstract

The invention relates to the technical field of organic photoelectric materials, and in particular, relates to an organic compound, an electronic element containing the same and an electronic device.The compound has a structure represented by a chemical formula 1', wherein one of R1, R2, R3 and R4 is a group defined in the specification, and the other three are selected from substituents such asalkyl, halogen and cyano; one of R5, R6, R7 and R8 is a group defined in the specification, the other three are selected from substituents such as alkyl, halogen and cyano, Y and Y1 are respectively and independently a group defined in the specification, and L and L1 are single bonds, aryl, heteroaryl and the like. By using the organic compound in an electronic component, the driving voltage, luminous efficiency, and life of the electronic component are improved.

Description

technical field [0001] The present invention relates to an organic compound, an electronic component and an electronic device including the organic compound. Background technique [0002] Organic electroluminescent devices have become a research hotspot in the field of flat panel display. Compared with liquid crystal displays, plasma displays, etc., organic electroluminescent devices have the advantages of wide viewing angle, fast response, low driving voltage, high luminous efficiency, and easy realization of ultra-thin and light weight. [0003] Common organic electroluminescent devices generally include an anode, a cathode, and an organic compound layer disposed between the two electrodes. When a voltage is applied between the two electrodes, holes and electrons are injected from the anode and cathode, respectively, and transported in the organic compound layer, and the holes and electrons meet to form excitons, which pass the radiation from the excited state to the grou...
