ORGANIC LIGHT EMITTING DEVICE WITH THERMALLY ACTIVATED DELAYED FLUORESCENT LIGHT EMITTING MATERIAL

摘要

The present disclosure is directed to organic electroluminescent devices comprising thermally activated emission material(s) in an emission layer. The present disclosure is also directed to compounds capable of providing thermally activated delayed fluorescence, and to emission layers comprising at least one of the compounds. The compounds may be used in organic layers such as emission layers of an organic electroluminescence device such as fluorescent OLEDs.
