Patent ID: 8716700

Claim:
An organic light-emitting diode luminaire comprising a first electrode, a second electrode, and an electroluminescent layer therebetween, the electroluminescent layer consisting essentially of: a host material capable of electroluminescence having an emission color that is blue green, wherein the host with blue-green emission color is a chrysene derivative having Formula II: wherein: Ar 1 and Ar 3 are the same or different and are aryl, and at least one of Ar 1 and Ar 3 has at least one alky substituent, with the proviso that there are no electron-withdrawing substituents; Ar 2 and Ar 4 are the same or different and are aryl; R 18 , R 19 , and R 21 are the same or different and are selected from the group consisting of H, D, and an electron-withdrawing group; R 20 is an electron-withdrawing group; R 22 through R 27 are the same or different and are selected from the group consisting of H, D, and alky and an electroluminescent dopant having an emission color that is red/red-orange; wherein the additive mixing of the two emitted colors results in an overall emission of white light.
