Abstract

New deep-blue iridium complexes, consisting of a heptafluoropropyl (HFP) substituent at the 3' position of 2',4''-difluorophenyl, have a deep HOMO level and decreased shoulder electronic transition and inhibit self-quenching due to the sterically hindered group without conjugation. An OLED using (HFP)2Ir(mpic) exhibited a maximum EQE of 21.4% with a CIE of (0.146, 0.165).
