AbstractThe subject invention is directed to tetradentate bis-(NHC carbenes) alkylene ligand Pt(II) complexes, tetradentate bis-(NHC carbenes) alkylene ligands, and its ligand precursors, for preparation of the Pt(II) complexes. The Pt(II) complexes show a deep blue emission with an improved quantum efficiency and can be used for fabrication of OLEDs with an electroluminescence layer that comprise the bis-(NHC carbenes) alkylene ligand Pt(II) complexes.
