Abstract

Novel heterocyclic compounds that impart improved luminescence efficiency characteristics such as low voltage, high luminance and long lifetime to organic light-emitting devices are described. Synthetic methods for the subject heterocyclic compounds are described. Methods for the construction of an organic light-emitting device comprising at least one of the subject heterocyclic compounds and comprising various hole transport layers, various electron transport layers and an emission layer are disclosed. The emission layer can comprise red, green, blue and white emission layers; one of said emission layers can comprise a phosphorescent compound. In certain embodiments, the heterocyclic compounds are useful as either fluorescent dopants or as phosphorescent hosts in the emission layer.
