ORGANOIRIDIUM COMPLEX FOR ORGANIC ELECTROLUMINESCENT ELEMENTS

ORGANOIRIDIUM COMPLEX FOR ORGANIC ELECTROLUMINESCENT ELEMENTS

The present invention relates to an organoiridium complex for an organic electroluminescent element in which a C-N ligand and an ancillary ligand are coordinated with iridium. This organoiridium complex contains a 2-(dibenzo[b,d]thiophen-4-yl)quinolinate ligand having at least one methyl group intro...

Beschreibung
Zusammenfassung:The present invention relates to an organoiridium complex for an organic electroluminescent element in which a C-N ligand and an ancillary ligand are coordinated with iridium. This organoiridium complex contains a 2-(dibenzo[b,d]thiophen-4-yl)quinolinate ligand having at least one methyl group introduced thereinto coordinated as the C-N ligand, and is represented by the following Formula. The present inventive organoiridiurn complex is suitable as a red emitting phosphorescent material for an OLED, has high photoluminescence quantum yield ΦPL, and is excellent in color purity.(In the aforementioned Formula, R1, R2, R3, R4, R5, R6, and R7 are each a methyl group or a hydrogen atom, provided that at least one of R1, R2, R3, R4 is a methyl group; and X-Y is the ancillary ligand.)
