Yeh, Shi-Jay published the artcileNew dopant and host materials for blue-light-emitting phosphorescent organic electroluminescent devices, Synthetic Route of 219508-27-7, the publication is Advanced Materials (Weinheim, Germany) (2005), 17(3), 285-289, database is CAplus.
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) phosphorophor. New host materials with higher glass-transition temperatures also enhance the OLED performance.
