THIAZOLE AND OXAZOLE CARBENE METAL COMPLEXES AS PHOSPHORESCENT OLED MATERIALS

摘要

The present invention relates to compounds comprising a heterocyclic carbin ligand. In particular, oxazoles or thioazocarbenes are used instead of the usual imidazolecarbenes. Such compounds can be used in OLEDs to provide devices with improved properties, such as stability and color-coordination. In addition, novel methods for synthesizing heterocyclic carbene metal complexes are provided.
