The authors have demonstrated highly efficient deep-blue phosphorescent organic light-emitting diodes (BPHOLEDs) using iridium(III) bis[(5-cyano-4-fluorophenyl)pyridinato-N,C-2']picolinate (FCNlrpic) as a blue emitter. FCNlrpic has a deeper-blue color than iridium(III) bis[4,6-(difluorophenyl)pyridinato-N,C-2']picolinate. The BPHOLEDs with FCNlrpic showed a maximum luminous efficiency of 19.00cd/A, a maximum external quantum efficiency of 10.70%, and Commission Internationale de L'Eclairage coordinates (CIEx,y) of (0.16,0.26).
