Synthetic example

[0216]In the synthesis examples described below, all temperatures are in degrees Celsius unless otherwise stated. Some reagents were purchased from commercial suppliers such as Aldrich Chemical Company, Arco Chemical Company and Alfa Chemical Company, and were used without further purification unless otherwise stated. The compounds of the synthetic methods not mentioned in this application are all raw material products obtained through commercial channels.

[0217] During purification, the chromatographic column is a silica gel column, and silica gel (100-200 mesh) is purchased from Qingdao Ocean Chemical Factory.

[0218] In each synthesis example, the measurement conditions of low-resolution mass spectrometry (MS) data are: Agilent 6120 quadrupole HPLC-M (column model: Zorbax SB-C18, 2.1 * 30mm, 3.5 microns, 6min, flow rate is 0.6mL / min. Mobile phase: 5%-95% (acetonitrile containing 0.1% formic acid) in (water containing 0.1% formic acid) ratio), using electrospray ionizat...

[0342] Embodiment 1 blue organic electroluminescent device

[0343] The anode was prepared by the following process: the thickness was The ITO substrate (manufactured by Corning) was cut into a size of 40mm × 40mm × 0.7mm, and it was prepared into an experimental substrate with cathode, anode and insulating layer patterns by using a photolithography process, using ultraviolet ozone and O 2 : N 2 Plasma surface treatment was performed to increase the work function of the anode (experimental substrate) and to remove scum.

[0344] F4-TCNQ was vacuum evaporated on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and HT-01 is evaporated on the hole injection layer to form a thickness of hole transport layer.

[0345] Vacuum-deposit HT-02 on the hole transport layer to form a thickness of electron blocking layer.

[0346] On the electron blocking layer, BH-01 and BD-01 are co-evaporated at a ratio of 98%: 2%, forming a thickness of...

Embodiment 2～32

[0351] An organic electroluminescent device was prepared in the same manner as in Example 1, except that the compound shown in Table 11 below was substituted for Organic Compound 2 of the present application, except when forming the electron transport layer.

Abstract

The invention relates to an organic compound, the organic compound has a structure as shown in the following formula (1), in the formula (1), R1 and R2 are the same or different from each other and are respectively and independently a substituted or unsubstituted alkyl group with 1-4 carbon atoms and a substituted or unsubstituted phenyl group; each Y is the same or different and independently has a structure represented by formula (2), X1, X2, X3, X4 and X5 are the same or different and independently are CR4 or N, and at least one of X1, X2, X3, X4 and X5 is N; m is selected from 1 or 2; n is selected from 1 or 2. The organic compound can be used as a hole blocking layer or an electron transport layer of an organic electroluminescent device.

Description

technical field [0001] The application belongs to the technical field of organic materials, and specifically provides an organic compound and an electronic component and an electronic device using the same. Background technique [0002] As a new generation of display technology, organic electroluminescent materials (OLED) have the advantages of ultra-thin, self-luminous, wide viewing angle, fast response, high luminous efficiency, good temperature adaptability, simple production process, low driving voltage, and low energy consumption. It has been widely used in industries such as flat panel display, flexible display, solid state lighting and vehicle display. [0003] An organic light emitting device generally includes an anode, a cathode and an organic material layer therebetween. The organic material layer is usually formed in a multilayer structure composed of different materials to improve the brightness, efficiency and life of the organic electroluminescent device. The...
