An OLED emitter having a complex of Structure I. The complex has a tungsten (VI) center and two coordination units which are independent or connected together. Each coordination unit coordinates to the center with a nitrogen-tungsten bond and an oxygen-tungsten bond. The tungsten (VI) emitter can be used in light-emitting devices.
The present invention relates to organic electroluminescent devices which comprise fluorene derivatives and spiro
bifluorene derivatives as matrix material for phosphorescent emitters.
A method for making metal (8-quinolinolate) complexes from air and moisture stable reagents is described. For example, the making of aluminum tris(quinolinolates), such as tris(8-hydroxyquinolinato), from aluminum (III) carboxylates, such as aluminum lactate and aluminum stearate, is described. Examples of bis and tris metal (8-quinolinolates) as well as single and mixed ligand complexes are given.
