Embodiment 1

[0235] Embodiment 1: the preparation of green organic electroluminescence device

[0236] The anode was prepared by the following process: the thickness of ITO was The ITO substrate is cut into a size of 40mm (length) × 40mm (width) × 0.7mm (thickness), and it is prepared into an experimental substrate with an anode and an insulating layer pattern by using a photolithography process, and ultraviolet ozone and O 2 :N 2 Plasma is used for surface treatment to increase the work function of the anode, and the surface of the ITO substrate is cleaned with an organic solvent to remove impurities and oil on the surface of the ITO substrate.

[0237] HAT-CN was vacuum evaporated on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and then vacuum-evaporated NPB on the hole injection layer to form a thickness of the first hole transport layer.

[0238] Compound 2 is vacuum evaporated on the first hole transport layer to form a thickness of ...

Embodiment 2-30

[0242] An organic electroluminescent device was prepared in the same manner as in Example 1, except that the compounds in Table 5 were used instead of Compound 2 used in Example 1 when forming the second hole transport layer.

Abstract

The invention relates to a nitrogen-containing compound, and an electronic component and an electronic device comprising the same. The nitrogen-containing compound contains fluorenyl, benzocycloalkyl with rich electron density is introduced to the 9 site of the fluorenyl, and the nitrogen-containing compound is applied to the organic electroluminescent device and can remarkably improve the performance of the device.

Description

technical field [0001] The application belongs to the technical field of organic materials, and in particular relates to a nitrogen-containing compound and electronic components and electronic devices containing the same. 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] Taking an organic electroluminescent device ...
