Abstract: Novel heteroleptic iridium carbene complexes are provided. The complexes have lower-than expected sublimation temperatures, which is beneficial for the processing of these materials in solid state applications. Selective substitution of the ligands provides for phosphorescent compounds that are suitable for use in a variety of OLED devices. The carbene complexes can also be used as materials in a hole blocking layer and/or an electron transport layer to improve device performance.
