Linear two-coordinate metalloorganic complexes composed of coinage metals (Cu, Ag, Au), electron accepting carbene and electron donating amide ligands have recently emerged as a promising emitter class for organic light emitting diode (OLED) applications.1 Here structural modifications of carbene-metal-amides (CMAs) are explored by introduction of novel thiazoline and imidazole-based carbene ligands (Figure 1). CMAs based on thiazoline ligands exhibit dual emission from monomer and excimer excited states allowing singleemissive-layer white electroluminescence.2 In the case of imidazole ligands the presence of auxiliary electron acceptors enables through-space charge transfer process, substantially decreasing the singlet-triplet energy gap thus lowering thermal activation barrier for thermally activated delayed emission (TADF) process.
