Description

technical field

[0001] The invention relates to an organic compound, in particular to an organic nitrogen heterocyclic derivative used in an organic electroluminescence device and its application in the technical field of electroluminescence display. Background technique

[0002] Organic electroluminescence technology, or organic light-emitting diode technology, is seen as the next generation display technology. Compared with traditional liquid crystal (Liquid Crystal Display, LCD) technology, there is no need for backlight illumination and color filters, and pixels can emit light by themselves and appear on a color display panel. Moreover, it has the characteristics of ultra-high contrast, ultra-wide viewing angle, curved surface, and thin profile.

[0003] Organic electroluminescent devices can be traced back to 1963 when Pope et al. studied blue electroluminescence with anthracene as a single crystal (10-20 μm). Because of the thick anthracene single crystal light-emitti...
