- NOVEL COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME
-
A novel compound of the present invention can be applied to a light-emitting layer, an electron-injecting layer, an electron-transporting layer, or a hole-inhibiting layer of an organic light-emitting device. The novel compound and the carbazole derivative of the present invention are used together as a host of the organic light-emitting device, thereby properly controlling the exciplex wavelength and maximizing the efficiency and the durability of the organic light-emitting device.COPYRIGHT KIPO 2016
