A pure blue OLED device with reduced driving voltage has been constructed from an emissive layer of doped 9,10-bis-(β-naphthyl)-anthrene (see Figure for formula), a hole-blocking/electron transport layer for carrier and exciton confinement, and a MgAg cathode with a thin LiF film on top to further decrease the driving voltage.
