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