Abstract

Disclosed is an organic compound which is represented by a general formula (I) shown in the description. L1-L10 are independently selected from a single bond, alkyl groups of C1-C30, aryl groups of C6-C60 and heteroaryl groups of C3-C60. The L1-L10 can be the same or different from each other. R1-R10 are independently selected from hydrogen, cyan, halogen, alkyl groups of C1-C30, substituted or unsubstituted aryl groups of C6-C60 and substituted or unsubstituted heteroaryl groups of C3-C60. The n1-n10 are integers of 1-3.

Description

technical field

[0001] The invention relates to a new organic heterocyclic compound, in particular to a class of organic compounds containing phenanthropyrimidine groups and their derivatives, and their 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 ...
