20110084599 | SINGLE TRIPHENYLENE CHROMOPHORES IN PHOSPHORESCENT LIGHT EMITTING DIODES - Novel triphenylene compounds are provided. Specific examples include multi-aryl-substituted triphenylenes. A preferred group of compounds 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. Some high triplet energy analogs are expected to work with deep blue phosphorescent dopants. 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. | 04-14-2011 |
20110227049 | PHOSPHORESCENT MATERIALS - Novel organic compounds containing a twisted aryl group are provided. In particular, the compounds provided contain a 2-phenylpyridine ligand having a twisted aryl group on the pyridine portion of the ligand. The compounds may be used in organic light emitting devices, particularly as emitting dopants. Devices comprising the compounds containing twisted aryl may demonstrate improved color, efficiency, stability and manufacturing. Additionally, methods are provided for making homoleptic Ir (III) compounds which may contain a twisted aryl. | 09-22-2011 |
20140042413 | PHOSPHORESCENT EMITTERS AND HOST MATERIALS WITH IMPROVED STABILITY - Iridium complexes with ligands containing twisted aryl groups having extended conjugation (i.e., the twisted aryl is substituted with an additional aryl group) and organic light emitting devices including the same are disclosed. The iridium complexes can be used in organic light emitting devices may provide improved stability color, lifetime and manufacturing. | 02-13-2014 |
20140103327 | HOST MATERIALS FOR ORGANIC LIGHT EMITTING DEVICES - 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. The compounds may be useful in phosphorescent organic light emitting devices. | 04-17-2014 |
