Light emissive materials incorporating quinolinolato metal complexes
Novel emissive materials suitable for organic light emitting devices are disclosed having a structure (L2M)n&#8212;X wherein L is a 2-alkyl-8-quinolinolate or 2-phenyl-8-quinolinolate ligand, M is a trivalent metal atom, n is an integer between 1 and 12. When n equals 1, X comprises a monovalent arylate emitter that contains at least one triarylamine group or a light emitting group with emission peak wavelength in the range of 500-750 nm. When n equals 2, X comprises a divalent arylate emitter that contains at least one triarylamine group or a light emitting group with emission peak wavelength in the range of 500-750 nm. When 3&lE;n&lE;12, X is an n-valent arylate group.
