Abstract:
The invention provides an OLED device including a cathode, an anode, and having there between a light-emitting layer, further including, between the cathode and the light emitting layer, a first layer containing a fluoranthene compound including one and only one fluoranthene nucleus and having no aromatic rings annulated to the fluoranthene nucleus, the fluoranthene nucleus having independently selected aromatic groups in the 7,10-positions and an azine group in the 8- or 9-position, provided that the azine group is not a phenanthroline group. The OLED device desirably includes a second layer containing an alkali metal or alkali metal compound, located between the cathode and the first layer. The OLED device can also include a polycyclic aromatic hydrocarbon compound in the first layer or in a third layer located between the first layer and the light-emitting layer. Devices of the invention provide improvement in features such as efficiency and drive voltage.
