Organic Light‐Emitting Diodes based on Charge‐Neutral Ru^II Phosphorescent Emitters

Abstract

The synthesis and characterization of a new series of charge-neutral RuII metal complexes are reported. The compound [Ru(ifpz)2(PPh2Me)2] is a very attractive candidate for the fabrication of saturated red phosphorescent organic light-emitting diode devices (see Figure) with high brightness and very low turn-on voltage.
