文摘

The first examples of BMes₂-functionalized NHC chelate ligands have been achieved. Their Pt(II) acetylacetonate complexes have been synthesized and fully characterized. These NHC-chelate Pt(II) compounds display highly efficient blue or blue-green phosphorescence in solution (桅 = 0.41鈥?.87) and the solid state (桅 = 0.86鈥?.90). Highly efficient electroluminescent devices based on these new Pt(II) compounds have also been fabricated.
