The (ppy)-based Pt(II) complex (Pt-1) with deprotonated 2-(diphenylphosphino) benzoic acid as an anionic ligand displays phosphorescence of monomers with a remarkably higher quantum yield than that of the corresponding iridium complex (Ir-1). A prototype OLED using Pt-1 exhibits high performance with an external quantum efficiency of 4.93%.
