Phosphorescent organic light emitting diodes with >20% external quantum efficiency have been demonstrated for the first time using a cyclometalated Pt(II) complex with a triarylboron group, i.e., acetylacetonato(5-dimesitylboryl-2-(phenyl)pyridyl)platinum(II), or Pt-BppyA. This unprecedented device performance is mainly attributed to the high quantum yield of the Pt(II) complex that is achieved by using a triarylboron moiety as well as to the highly optimized double emission zone device architecture.
