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 ³MLCT 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.
