    摘要： An OLED device comprising a cathode, an anode, and having therebetween a light emitting layer and an electron-injecting layer, where (a) the light emitting layer contains a host and up to 50 volume % of a light-emitting fluoranthene compound with a 7,10-diaryl substituted fluoranthene nucleus having no aromatic rings annulated to the fluoranthene nucleus; and (b) the electron-injecting layer being located between the cathode and the light-emitting layer contains an organic alkali metal compound. It provides reduced drive voltage, operational stability and luminance of OLED devices.

    摘要： An OLED device comprises a cathode, an electron-transporting layer (ETL), a light-emitting layer (LEL) containing a fluorescent light-emitting material, a hole-transporting layer (HTL), and an anode, in that order, wherein the ETL comprises a mixture of compounds, including a first compound and at least one second compound, and wherein there is present a hole blocking layer (HBL) adjacent to the LEL on the cathode side. It provides a reduced drive voltage with comparable color hue. The first compound is present in an amount of 50% to 90% by volume and is represented by Formula (2): Wherein R1 and R4 represent the substituent and neither are hydrogen; R2 and R3 represent hydrogen; Ar1 and Ar4 represent the same aromatic group; and Ar2 and Ar3 represent the same aromatic group.
