FIrPic, highly efficient phosphorescent dopant material for OLED devices

High purity and available online for priority dispatch


Bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium, abbreviated as FIrPic, F2IrPic or Ir(difppy)2(pic), is one of the most investigated bis-cyclometallated iridium complexes, in particular in the context of organic light emitting diodes (OLEDs). This is because of its attractive sky-blue emission, high emission efficiency, and suitable energy levels as a phosphorescent dopant material.
