Problems solved by technology

Although these materials have played an important role in the development of OLED technology, some materials are still widely used in laboratories and PMOLED production lines. These materials can no longer meet the requirements. At present, light-emitting devices using existing organic materials either require higher driving voltages, or lead to low luminous efficiency of organic electroluminescent devices, and the device life is not satisfactory.

Abstract

The invention provides a compound of general formulae (I) and (II), wherein A1 and A2 are independently selected from C1-12 alkyl, C6-60 substituted or unsubstituted aryl and C10-60 substituted or unsubstituted condensed ring aryl, separately; the substituted aryl specifically means that the substituent is selected from C1-6 alkyl, halogen and CN or Si(R2)3, and R2 is selected from C1-6 alkyl; andthe substituted condensed ring aryl specifically means that the substituent is selected from C1-6 alkyl, halogen and CN or Si(R2)3, and R2 is selected from C1-6 alkyl. The compound of the general formulae can be used in organic electroluminescence devices.

Description

technical field [0001] The invention relates to a novel organic compound, in particular to a compound used in an organic electroluminescent device and its application in the organic electroluminescent device. 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 ...
