Abstract

The invention discloses a general formula compound represented by the following formula (1), wherein R<1> is selected from hydrogen, C6-C60 substituted or non-substituted aryl or polycyclic aromatic groups, and C3-C60 substituted or non-substituted heteroaryl or polyheterocyclic aromatic groups. Hy is represented by the following formula Hy1 or Hy2. The invention also provides an organic electroluminescent device, wherein the organic electroluminescent device includes the general formula compound and can achieve efficient and balanced charge carrier transmission performance.

Description

technical field [0001] The invention relates to a compound with a general formula, in particular to a novel pyridine biindole derivative organic compound, and to an organic electroluminescent device using the compound of the invention. 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 li...
