摘要:
Organic devices comprising an organic layer, wherein the organic layer is non-electroluminescent and comprises a cross-linked metal complex. The cross-linked metal complex may be formed by cross-linking a cross-linkable iridium complex, which comprises a set of ligands coordinated to a central iridium atom. One or more of the ligands have attached thereon, one or more polymerizable groups that are able to polymerize with other molecules to form intermolecular covalent bonds. In some cases, the organic layer may also comprise a dopant. Also provided are a method of making an organic light-emitting device, an iridium complex, and an organic-light emitting device using certain iridium complexes.

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.

摘要:
Organic electronic devices comprising a covalently bonded organic/inorganic composite layer. The composite layer may be formed by the reaction of a metal alkoxide with a charge transport compound having one or more hydroxyl groups. Examples of metal alkoxides that can be used include vanadium alkoxides, molybdenum alkoxides, titanium alkoxides, or silicon alkoxides. This composite layer can be used for any of the various charge conducting layers in an organic electronic device, including the hole injection layer.
摘要:
Organometallic compounds comprising an emissive core and one or more poly-phenylene branches linked to the emissive core. Host moieties are provided as pendant groups on the branches. In some cases, the poly-phenylene chain is linked in meta configuration to reduce π-conjugation in the chain. Suitable host moieties for use in the organometallic compound include those that contain carbazole or triphenylene structures. The quantity and types of host moieties on the organometallic compound may be varied to tune the molecular weight ratio of the host moieties relative to the emissive core. In some cases, the organometallic compound is sufficiently soluble in organic solvents to permit solution processing. Also provided are organic electronic devices comprising organometallic compounds of the present invention and methods for making an organic electronic device using organometallic compounds of the present invention.

Novel organometallic compounds are provided, which include a 2-phenylpyridine iridium (Irppy) complex having alkyl and/or aryl substituted ligands and a heteroleptic or a homoleptic nature. These materials may be advantageously used in OLEDs to tune evaporation temperature and solubility, narrow emission, and increase device efficiency.
