Problems solved by technology

Traditional fluorescent dyes emit light through the relaxation of the singlet state to the ground state after receiving the energy transfer from the host material, but because the singlet state excitons only occupy 25% of the ratio, the luminous efficiency is low

Abstract

The invention discloses a pyrene derivative and application thereof to an organic luminescent material. The invention also provides an organic electroluminescent light-emitting device, wherein the device comprises an organic electroluminescent compound. According to the compound of the pyrene derivative disclosed by the invention, by introducing a pyrene structure, the high-efficient and balancedtransmission performance of a current carrier is realized.

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...
