Disclosed are organic electroluminescent devices comprising a substrate, an anode and a cathode disposed over the substrate, an emission layer (EML) disposed between the anode and the cathode, a hole-transport layer (HTL) disposed between the anode and the emission layer, and an electron-transport layer (ETL) disposed between the cathode and the emission layer. The EML and either the HTL, the ETL, or both the HTL and the ETL include a derivative of anthracene as a color-neutral dopant. A color-neutral dopant is a dopant whose presence does not alter the electroluminescent color of the device.
