Abstract

In this work we present the synthesis and characterization of several novel osmium complexes of the form [Os(N-N)2L-L]2+ 2X- designed for organic light emitting device (OLED) applications. In the complex notation N-N represents a derivative of 2,2′-bipyridine or 1,10-phenanthroline and L-L represents a strong π-acid arsine or phosphine ligand. The complexes feature 3 MLCT emission that ranges from 611-650 nm, which makes them suitable as an emission source for red OLEDs. Phosphorescent quantum yields as high as 45% and emission lifetimes as short as 400 nanoseconds have been reached.
