    摘要: The invention provides an OLED device including a cathode, an anode, and having therebetween a light-emitting layer, further including, between the cathode and the light emitting layer, a first layer containing a fluoranthene-macrocyclic compound. The fluoranthene-macrocyclic compound includes a fluoranthene nucleus having the 7,10-positions connected by a linking group. The fluoranthene nucleus can be further substituted, provided substituents in the 8- and 9-positions cannot combine to form a five-membered ring group. The OLED device includes at least one layer, between the light-emitting layer and the cathode, containing an alkali metal material. Desirably, the OLED device includes an organic alkali metal compound present in the first layer or in a second layer located between the cathode and the first layer. The OLED device can include an anthracene derivative that is present in the first layer, in addition to the fluoranthene-macrocyclic compound. Devices of the invention provide improvement in features such as efficiency and drive voltage.
