Abstract

The invention discloses pyrene derivatives and their application in organic luminescent materials. The invention also provides an organic electroluminescent device, which includes the organic electroluminescent compound. The compound of the present invention realizes efficient and balanced carrier transport performance by introducing a pyrene structure.

Description

technical field [0001] The invention relates to a novel pyrene derivative organic compound, in particular to a compound used in organic electroluminescent devices and its application in organic electroluminescent devices. Background technique [0002] 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 needs a backlight source, has a large viewing angle, low power, and its response speed can reach 1000 times that of a liquid crystal display, but its manufacturing cost is lower than that of a liquid crystal display with the same resolution. Therefore, organic electroluminescent devices have broad application prospects. [0003] With the continuous advancement of OLED technology in the two major fields of lighting and dis...
