Abstract:
Novel organic compounds comprising a substituted anthracene or acridine ligand are provided. In particular, the compound includes an anthracene ligand substituted at the 9 and 10 positions. The compound may be used in organic light emitting devices to provide devices having improved efficiency and lifetime. In particular, these compounds may be especially beneficial for use in blue-emitting OLEDs.
Abstract:
Novel organic compounds comprising azaborine are provided. In particular, the compounds comprise a dibenzo-1,4,-azaborine core having a phenyl substituent on the boron atom, and aryl or heteroaryl substituents at positions 2 and 6 of the phenyl substituent. These compounds may be advantageously used in organic light-emitting devices to provide improved efficiency and lifetime.
Abstract:
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.
Abstract:
Phosphorescent organometallic complexes comprising phenylquinolinato ligands are provided. High efficiency organic light emitting devices comprising these compounds are also described.
