Abstract

Preparation and characterization of a new class of emissive Os(II) complexes is reported by Hao-Wu Lin, Yun Chi, Pi-Tai Chou, and co-workers on page 3491. The complexes all show bright emission spanning the visible region from green to saturated red and a series of solution-processed organic light-emitting diodes (OLEDs) using the complexes as the dopant are successfully fabricated, demonstrating excellent device performance with an external quantum efficiency of 15% and power efficiency of up to 50 lm W−1.
