Embodiment 1

[0190] The substrate containing the Ag alloy light reflection layer and the anode ITO (thickness 15nm) of the organic electroluminescence element is cut into a size of 40mm (length) × 40mm (width) × 0.7mm (thickness), and the photolithography process is used to cut it Prepare an experimental substrate with a cathode 5, an anode 1 and an insulating layer pattern, use ultraviolet ozone and O2:N2 plasma for surface treatment to increase the work function of the anode 1 (experimental substrate), and use an organic solvent to clean the surface of the ITO substrate, To remove scum and oil on the surface of the ITO substrate, the organic solvent can be ethanol, acetone, or isopropanol. Of course, it can also be other organic solvents, which will not be listed here. It should be noted that the ITO substrate can also be cut into other sizes according to actual needs, and the size of the ITO substrate in the present disclosure is not specifically limited here.

Abstract

The invention provides a nitrogen-containing compound, an electronic component and an electronic device, and belongs to the technical field of organic materials. The nitrogen-containing compound is shown as a formula I, and can reduce the working voltage of a device, improve the efficiency of the device and prolong the service life of the device.

Description

technical field [0001] The present disclosure relates to the technical field of organic materials, in particular, to a nitrogen-containing compound, an electronic component and an electronic device. Background technique [0002] In recent years, with the development of semiconductor technology, electronic components have been widely used. For example, an organic electroluminescent device (OLED, Organic electroluminescent device) has gradually entered people's field of vision as a new generation of display devices. Compared with traditional display devices, organic electroluminescent devices have great advantages in voltage characteristics, luminous brightness, luminous efficiency, color quality, response speed, viewing angle, etc., and are low in cost, so they have broad market prospects. [0003] In order to improve the brightness, efficiency and lifespan of an organic electroluminescent device, a laminated structure is usually used in the device, and its structure mainly i...
