Description

technical field

[0001] The invention relates to a novel organic compound, in particular to an organic luminescent material, and further discloses its preparation method and application for preparing an organic electroluminescence device. Background technique

[0002] Electroluminescence (EL) refers to the phenomenon that luminescent materials emit light under the action of an electric field and are excited by current and electric field. It is a luminescence process that directly converts electrical energy into light energy. Organic electroluminescent display (hereinafter referred to as OLED) has a series of advantages such as self-luminescence, low-voltage DC drive, full curing, wide viewing angle, light weight, simple composition and process, etc. Compared with liquid crystal display, organic electroluminescent display is not It requires a backlight source, has a large viewing angle and low power, and its response speed can reach 1000 times that of a liquid crystal display,...
