Transition metal carbene complexes and the electroluminescent application thereof
This invention provides transition metal carbene complexes and the electroluminescent application thereof. Through employing different N^N heteroleptic ligand, as the following, the transition metal carbene complex can display wide-range color tuning ability from deep blue to red. The mentioned transition metal carbene complex can be applied in luminescent device, and the luminescent device can display wide-range color tuning ability with high luminescent efficiency while employing different N^N heteroleptic ligand in the transition metal carbene complex.
