摘要:
An organic emissive layer is provided. Also provided is a device in which the organic emissive layer is disposed between an anode and a cathode. The organic emissive layer includes a phosphorescent material and triphenylene compound or a compound having a repeat unit having a triphenylene moiety. The triphenylene is optionally substituted. The substituents may be the same or different and each is selected from the group consisting of alkyl, aryl, fused aryl, substituted aryl, alkenyl, alkynyl, and heteroalkyl. Triphenylene compounds are also provided.
