    Efficient organic light‐emitting diodes (OLEDs) incorporating IrIII bis(4,6‐difluorophenylpyridinato)‐3‐(trifluoromethyl)‐5‐ (pyridin‐2‐yl)‐1,2,4‐triazolate (FIrtaz) and IrIII  bis(4,6‐difluorophenylpyridinato)‐5‐(pyridin‐2‐yl)‐1H‐tetrazolate (FIrN4) demonstrate higher‐purity blue‐light emission than the long‐known IrIII bis(4,6‐difluorophenylpyridinato)picolate (FIrpic) phosphorophore. New host materials with higher glass‐transition temperatures were also found to enhance the OLED performance.
