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 charge transport material and/or host material for phosphorescent emitters in electroluminescent devices, the compounds of formula I may provide improved efficiency and reduced driving voltage of electroluminescent devices.
