Organic Electroluminescent Devices with 8-Hydroxyquinoline Derivative-Metal Complexes as an Emitter

Abstract
Organic electroluminescent (EL) devices with 8-hydroxy-quinoline derivative-metal complexes (Znq2, Beq2, Mgq2, ZnMq2, BeMq2 and AlPrq3) as the emitter have been developed. The emissions of these devices are green or yellow. These devices have a luminance of more than 3000 cd/m2. In particular, the EL device with Znq2 has a luminance of 16200 cd/m2.
