Single triphenylene chromophores in phosphorescent light emitting diodes

摘要

The present invention is directed to novel compounds comprising a triphenylene core. The compounds may be useful in phosphorescent organic light emitting devices. Also provided is an organic electroluminescent device comprising an anode, a cathode, and an emissive layer between the anode and the cathode, the emissive layer comprising a phosphorescent material and a compound having a repeat unit, the repeat unit containing a triphenylene moiety.
