Abstract

  • A new family of hybridized local and charge-transfer (HLCT) emitters bearing a pyrene structural unit has been made for deep-blue OLED device.
  • Deep-blue OLEDs based on them achieved high brightness over 10000 cd m-2, high maximum external quantum efficiency over 10.5%, and high maximum exciton utilization efficiency approaching 100%, with CIE coordinates of (0.152, 0.065).

Materials & Devices

Device: ITO/HAT-CN (6 nm)/HAT-CN (0.2 wt%):TAPC (50 nm)/ TPP-TXO2:TcTa (12 wt%, 10 nm)/emitter:26DCzPPy (12 wt%, 10 nm)/Tm3PyP26PyB (50 nm)/LiF (1 nm)/Al (100 nm)
