Embodiment 2～7

[0297] An organic electroluminescence device was fabricated by the same method as in Example 1, except that the compounds shown in Table 7 were each used in forming the first hole transport layer (HTL1). Device performance is listed in Table 7.

Embodiment 8

[0310] The anode was prepared by the following process: the thickness of ITO was The ITO substrate (manufactured by Corning) was cut into a size of 40mm (length) × 40mm (width) × 0.7mm (thickness), and it was prepared into an experimental substrate with cathode, anode and insulating layer patterns by using a photolithography process. 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.

[0311] HAT-CN was vacuum evaporated on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and a layer of NPB is evaporated on the hole injection layer to form a thickness of The first hole transport layer (HTL1).

[0312] Then vacuum evaporate compound 113 on the first hole transport layer to form a thickness of The second hole transport layer (HTL2).

[0313] Then vapor-deposit 4,4'-N,N'-dicarbazole-biphenyl (referred to as "CBP") on the second hole tra...

Description

technical field [0001] The application belongs to the technical field of organic materials, and specifically provides an aromatic amine compound, an electronic component and an electronic device using the compound. Background technique [0002] With the development of electronic technology and the progress of material science, the application range of electronic components for realizing electroluminescence or photoelectric conversion is becoming wider and wider. Such electronic components generally include a cathode and an anode oppositely arranged, and a functional layer arranged between the cathode and the anode. The functional layer is composed of multiple organic or inorganic film layers, and generally includes an energy conversion layer, a hole transport layer located between the energy conversion layer and the anode, and an electron transport layer located between the energy conversion layer and the cathode. [0003] For example, when the electronic component is an or...
