Description

technical field

[0001] The invention relates to the technical field of organic electroluminescence display, specifically discloses a novel sulfur-containing organic electrophosphorescence luminescence material, and also discloses its application in organic electroluminescence devices. Background technique

[0002] Electroluminescence display devices can be divided into inorganic electroluminescence display devices and organic electroluminescence display devices according to the different materials constituting the light-emitting layer. Compared with inorganic EL display devices, organic EL display devices have incomparable advantages, such as full-color emission in the visible spectral range, extremely high brightness, extremely low driving voltage, fast response time, and simple fabrication craftsmanship, etc.

[0003] The research on organic electroluminescence started in the 1860s, when Pope first realized electroluminescence on anthracene single crystals, but at that ti...
