Useful:

• Description: 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.
• Uses: FIrpic is a light blue heteroleptic triplet emitter.This material is typically doped into host matrices such as tetra-aryl silanes and short conjugation length carbazole derivatives in OLEDs; showing a good quantum efficiency. suzuki reaction
