Description

technical field

[0001] The invention relates to the technical field of organic electroluminescent display, specifically discloses a novel organic electroluminescent material and its application in organic electroluminescent devices. Background technique

[0002] Electroluminescent display devices can be divided into inorganic electroluminescent display devices and organic electroluminescent display devices according to the difference in the constituent materials of the light-emitting layer. Compared with inorganic electroluminescent display devices, organic electroluminescent display devices have incomparable advantages, such as full-color emission in the visible spectrum range, extremely high brightness, extremely low driving voltage, fast response time, and simple fabrication. craft etc.

[0003] The research on organic electroluminescence started in the 1860s. Pope realized electroluminescence on anthracene single crystal for the first time, but at that time the driving ...
