Embodiment 1

[0259] Embodiment 1: Preparation of red organic electroluminescent device

[0260] The anode was prepared by the following process: the thickness of ITO / Ag / ITO was The ITO substrate 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 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 organic solvents can be used to clean the surface of the ITO substrate to remove impurities and oil on the surface of the ITO substrate.

[0261] 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.

[0262] On the first hole transport layer, compound HT-1 is vacuum evaporated to form a thickne...

Embodiment 2-63

[0266] An organic electroluminescent device was prepared by the same method as in Example 1, except that the compound in Table 12 below was used instead of Compound 1 in Example 1 when preparing the organic light-emitting 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 disclosed by the invention contains indolocarbazole, oxadiazole (thiadiazole) and a triazine group. The compound disclosed by the invention has relatively high electron mobility; and meanwhile, the compound has excellent hole transport performance. When the nitrogen-containing compound is used as a main body material, the balance of holes and electrons in an organic light-emitting layer can be improved, and the performance of a device can be remarkably improved.

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. 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 fie...
