Embodiment 1

[0216] Embodiment 1: Preparation of red organic electroluminescent device

[0217] Anode preparation: the thickness of ITO / Ag / ITO is 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 a cathode, an anode and an insulating layer pattern by using a photolithography process; 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.

[0218] 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.

[0219] On the first hole transport layer, compound HT-1 is vacuum evaporated to form a thickness of the second hole tr...

Embodiment 2-31

[0225] When forming the red light-emitting layer, an organic electroluminescent device was fabricated by the same method as in Example 1, except that the compound (Compound X) shown in Table 12 was substituted for Compound 1 in Example 1.

Abstract

The invention relates to an organic compound, an electronic device comprising the same, and an electronic apparatus comprising the electronic device. The structural formula of the organic compound is shown as a chemical formula 1, and the organic compound is applied to the electronic device and can remarkably improve the performance of the electronic device.

Description

technical field [0001] The application belongs to the technical field of organic materials, and in particular relates to an organic compound and an electronic device and electronic device containing the same. Background technique [0002] An organic electroluminescence device, such as an organic light emitting diode (OLED), generally includes 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 organic light-emitting layer, a hole transport layer, an electron transport layer, and the like. When a voltage is applied to the cathode and anode, the two electrodes generate an electric field. Under the action of the electric field, the electrons on the cathode side move to the electroluminescent layer, and the holes on the anode side also move to the light-emitting layer, and the electrons and holes combine in the electr...
