Beschreibung
Zusammenfassung:A light emitting composition comprising a central platinum group transition metal coordinated to a bridged tetradentate ligand comprised of chelating bis(azinyl)amine groups. A six-membered heteroatom ring is formed through coordination of the chelating ligand with the transition metal. An electron donating moiety serves as a bridge between the bis(azinyl)amine groups. The electron donating moiety can include amine or aryl groups. The platinum group transition metal may be selected from the group consisting of platinum, palladium, iridium, rhodium, ruthenium, and osmium. Additionally, OLED devices are provided, each of the OLED devices comprising a light emitting layer that includes one of the light emitting compositions.
