Abstract

The invention relates to a novel organic compound, particularly to a compound for an organic electroluminescent device, and the organic electroluminescent device adopting the compound, wherein the novel organic compound has a structure as shown in the following formula (1), Ar1 and Ar2 are respectively and independently selected from one of substituted or unsubstituted C6-C30 aryl and substitutedor unsubstituted C3-C30 electron-deficient heteroaryl, and at least one of Ar1 and Ar2 is selected from electron-deficient heteroaryl. When the compound provided by the invention is used as an electron transport layer material in an OLED device, excellent device performance and stability are shown. The invention also discloses an organic electroluminescent device adopting the compound with the general formula.

Description

technical field [0001] The present invention relates to a novel organic compound, in particular to a compound used in organic electroluminescent devices and organic electroluminescent devices using the compound. 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 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, 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 in the two major fields of lighting and display, people ar...
