Star-type triamine compound and organic electroluminescent device thereof

Abstract

The invention provides a star triamine compound and an organic electroluminescent device thereof, and particularly relates to the technical field of organic electroluminescent materials. The star-type triamine compound provided by the invention has relatively high hole mobility, can effectively improve a carrier transport imbalance phenomenon, and can effectively limit electrons in a light-emitting layer, so that a device has relatively high light-emitting efficiency; and when the material is used as a covering layer material, the material has relatively high refractive index and very good thermal stability, and aging of a device can be delayed, so that the service life of the device is effectively prolonged. In conclusion, the star-shaped triamine compound provided by the invention can be widely applied to the fields of panel display, illumination light sources and the like, and has a good application prospect.
