A device is provided, having an anode, a cathode, and two adjacent organic layers disposed between the anode and the cathode. One organic layer is a phosphorescent emissive material. The other organic layer may comprise an aromatic hydrocarbon material, comprising an aromatic non-heterocyclic hydrocarbon core optionally substituted, and wherein the substituents are the same or different, and each is selected from the group consisting of alkyl, alkenyl, alkynyl, aryl, heteroalkyl, substituted aryl, substituted heteroaryl and heterocyclic groups. The second organic layer may comprise a material having a molecular dipole moment less than about 2.0 debyes, such that the device has an unmodified external quantum efficiency of at least about 3% and a lifetime of at least about 1000 hours at an initial luminance of about 100 to about 1000 cd/m2.
