Fabrication and Characterization of Organic Electroluminescent Devices Introducing New Blue Emitting Materials

摘要

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.
