  • Publication number: 20140103327
    Abstract: Disclosed is an organic electroluminescent device including an anode, a cathode, and an emissive layer between the anode and the cathode, the emissive layer including a phosphorescent material and a compound having a repeat unit that contains a novel triphenylene moiety. A preferred group of the novel triphenylene moiety are triphenylenes that are substituted with a non-fused aryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups and alkyl groups. A further preferred group of compounds are triphenylenes that are substituted with a non-fused heteroaryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl or heteroaryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups.
