    摘要： The invention provides an OLED device including a cathode, an anode, and having therebetween a light-emitting layer, further includes, between the cathode and the light emitting layer: a) a first layer containing a silyl-fluoranthene compound including a fluoranthene nucleus having a silicon atom bonded to the 8- or 9-position, and wherein the silicon atom is further bonded to three independently selected substituents; and b) a second layer, located between the first layer and the cathode and contiguous to the first layer, and wherein: i) the second layer contains an alkali metal or an organic alkali metal compound; or ii) the second layer contains an azine compound. Embodiments of the invention can provide an OLED device with improved luminance and reduced drive voltage.
