摘要:
Novel phosphorescent heteroleptic iridium complexes with substituted phenylquinoline ligands are provided. The alkyl substitution on the phenylquinoline ligands together with larger alkyl substituents on the acetylacetone-derived ligands produces complexes with improved properties that are useful when incorporated into OLED devices.
摘要:
Compounds are provided that comprise a ligand having a 5-substituted 2-phenylquinoline. In particular, the 2-phenylquinoline may be substituted with a bulky alkyl at the 5-position. These compounds may be used in organic light emitting devices, in particular as red emitters in the emissive layer of such devices, to provide devices having improved properties.
摘要:
Compounds comprising the formula L1L2MX wherein L1, L2, and X are distinct bidentate ligands that form an octahedral complex on the metal M, wherein M is a metal with an atomic weight greater than 40. Compounds of this formula are sublimated more facilely than octahedral metal complexes where L1, L2, and X are not distinct bidentate ligands. Organic light emitting devices are also described wherein the emissive layer may comprise a host material containing an emissive molecule of formula L1L2MX, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including iridium complexes of the formula L1L2IrX wherein L1, L2, and X are distinct bidentate ligands.
摘要:
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.

摘要:
The present invention provides pyrazine derivatives that inhibit tyrosine kinase activity. Certain pyrazine derivatives are selective inhibitors of vascular endothelial growth factor (VEGF) receptor tyrosine kinase. The present invention also provides pharmaceutical formulations containing the pyrazine derivatives and methods of use of these formulations as anti-tumor agents and to treat solid-tumor cancers, angiogenesis, diabetic retinopathy, rheumatoid arthritis, endometriosis and psoriasis.
