Wide-Range Color Tuning of Iridium Biscarbene Complexes from Blue to Red by Different N boolean AND N Ligands: an Alternative Route for Adjusting the Emission Colors
Four new iridium biscarbene complexes with different N boolean AND N ligands showing very different emission colors from deep-blue to red are synthesized. The emission colors are mainly controlled by the N boolean AND N ligands. The electroluminescent devices using these complexes as dopant emitters exhibit extremely high efficiencies.
