Abstract
Various organic electroluminescent devices were fabricated using distyryl biphenyl arylene derivatives (DBA). To improve thermal stability of devices and quantum efficiency, poly(N-vinylcarbazole) (PVK) and poly(4,4′-oxydiphenylene pyromellitimide) (PMDA-ODA PI) were introduced onto the emitting layer by the spin coating method. The device performance was discussed.
