Abstract

The present invention provides a new organic electroluminescent material and an organic electroluminescent device using the same, wherein the organic electroluminescent material is represented by a general formula (1), and Z, X<1>-X<2>, Y<1>-Y<8>, R<1>-R<3>, Ar, n, m and p are defined in the specification.

Description

technical field [0001] The present invention relates to a new 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 display, people pay mor...
