摘要： 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.

摘要： A compound of the general formula (I), a process for the production of the compound and its use in electronic devices, especially electroluminescent devices. Improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices are provided when the compound of formula I is used as host material for phosphorescent emitters in electroluminescent devices.

摘要： The present invention relates to compounds of formula a process for their production and their use in electronic devices, especially electroluminescent devices. When used as host material for phasphorescent emitters in electroluminescent devices, the compounds of formula I may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
