DEEP-BLUE PHOSPHORESCENT IRIDIUM COMPLEX USING AN N-METHYLIMIDAZOLYL TRIAZOLE ANCILLARY LIGAND

摘要

The present invention relates to a blue phosphorescent iridium complex as expressed in chemical formula 1. The iridium complex of the present invention may exhibit a deeper blue color in a blue light-emitting region, and significantly improve phosphorescent quantum yield and light-emitting efficiency as compared to conventional iridium complexes. The light-emitting material comprising such an iridium complex may be used in a light-emitting layer of an organic light-emitting diode, and used in a display device.
