Disclosed are electroluminescent devices that comprise organic layers that contain certain organic compounds containing one ore more pyrimidine moieties. The organic compounds containing one ore more pyrimidine moieties are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.

triplet states while maintaining frontier molecular orbital levels, and thereby optimizing their optoelectronicproperties. Employing these TADFemitters results in a green fluorescent organic light‐emittingdiode (OLED) that exhibits a peak forward‐viewing externalquantumefficiency (EQE) close to 25 % and a slowefficiency roll‐off characteristic at high luminance.
