This invention relates to the field of organic electroluminescent materials, specifically to an
iridium metal complex, and more particularly to an
iridium metal complex for deep red-near-
infrared emission and its applications, as well as organic electroluminescent devices using the
iridium metal complex of this invention. The iridium metal complex of this invention has the structure shown in formula (1).
OLED devices prepared using the iridium metal complex of this invention exhibit higher luminous efficiency and better lifespan, demonstrating promising application prospects.
