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 electro- luminescent devices.
The present invention relates to novel organic compounds containing a triphenylene and a carbazole. The compounds are useful for organic light-emitting diodes. The compounds are also useful for charge-transport and charge-blocking layers, and as hosts in the light-emissive layer for organic light emitting devices (OLEDs).
