Description

technical field

[0001] The invention belongs to the technical field of organic photoelectric materials, and relates to an organic compound and its preparation method and application. Background technique

[0002] Compared with traditional technologies, OLED devices have many advantages such as low driving voltage, high luminous efficiency, high contrast, high color saturation, wide viewing angle and fast response time. Today's OLED devices include multiple layers of hole injection layer, hole transport layer, light emitting layer, hole blocking layer, electron transport layer and electron injection layer, and are matched with suitable electrodes. These layers are composed of the following materials: Hole injection materials, hole transport materials, luminescent materials, hole blocking materials, electron transport materials and electron injection materials. Among them, the OLED light-emitting layer made by doping has advantages in the luminous efficiency of the device, so ...
