Patent number: 7759490Abstract: There is disclosed herein phosphorescent compounds, uses thereof, and devices including organic light emitting diode (OLEDs) including such compounds. Compounds of interest include: wherein A is Os or Ru The anionic chelating chromophores N^N, which are formed by connecting one pentagonal ring structure containing at least two nitrogen atoms to a hexagonal pyridine type of fragment via a direct carbon-carbon linkage. L is a neutral donor ligand; the typical example includes carbonyl, pyridine, phosphine, arsine and isocyanide; two neutral L's can also combine to produce the so-called chelating ligand such as 2,2?-bipyridine, 1,10-phenanthroline and N-heterocyclic carbene (NHC) ligand, or bidentate phosphorous ligands such as 1,2-bis(diphenylphosphino)ethane, 1,2-bis(diphenylphosphino)benzene. L can occupy either cis or trans orientation.Type: GrantFiled: July 11, 2008Date of Patent: July 20, 2010Assignees: National Research Council of Canada, National Tsing Hua UniversityInventors: Ye Tao, Yun Chi, Yung-Liang Tung, Arthur Carty, Pi-Tai Chou
