Abstract
Novel iridium complexes containing triazole and tetrazole carbene ligands are described. These metal complexes additionally contain dibenzo moieties such as dibenzothiophene and dibenzofuran, and the complexes have overall improved properties such as more saturated blue emission when used as emissive compounds in OLED devices.
