Abstract: Novel electroluminescent devices containing bicarbazole triazine compounds as emissive dopants are described. Devices incorporating this class of compounds exhibit delayed fluorescence characteristics that showed EQE's far exceeding the theoretical limit for a conventional fluorescent device.

Abstract: An OLED device includes, in order, an electron blocking layer, an organic emissive layer, and a hole blocking layer. Its organic emissive layer contains at least four components: an electron transporting compound, a host, a hole transporting compound, and an emitting compound capable of phosphorescence emission at room temperature. The emitting compound has HOMO energy level of 5.2 eV or lower and a LUMO energy level of 2.5 eV or higher.
