Abstract
The present invention provides conductive metal-ligand coordination complexes that are useful in a variety of electronic devices. For example, such complexes are useful in organic light emitting devices composed of one or more layers of organic material between two conductors. The use of metal-ligand coordination complexes of the present invention as the cathode, replaces the more typically employed reactive metals, which function as the electron injecting contact, and provides for improved or longer-lived devices.
