Abstract
Provided am compounds comprising a carbocyclic or heterocyclic 6-membered ring as the central moiety to which at least two amine groups am directly substituted, wherein each amine group comprises at least two substituted or unsubstituted aryl or heteroaryl groups which are fused together to form a ring. Also provided are formulations comprising these compounds. Further provided are organic light emitting devices (OLEDs) and related consumer products that utilize these compounds.
