Abstract
This invention relates to an iridium metal complex. The iridium metal complex comprises no more than three 1,3-dihydro-2H-benzo[d]imidazol-2-ylidene based carbene cyclometalate ligands. The iridium metal complex provides a blue emission. This is useful for organic light emitting diode (OLED) components where blue emitters have trailed behind the advances of red and green emitters.
