Abstract

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).
