TRANSITION METAL CARBENE COMPLEXES AND THE ELECTROLUMINESCENT APPLICATION THEREOF

摘要

This invention provides a transition metal carbene complexes and the electroluminescent application thereof. Through employing different N̂N heteroleptic ligand, 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 N̂N heteroleptic ligand in the transition metal carbene complex.
