title: Robust phosphorescent platinum(II) complexes containing tetradentate O^N^C^N ligands: excimeric excited state and application in organic white-light-emitting diodes.
abstract: The bright white lights: A series of highly robust platinum(II) complexes supported by tetradentate O N C N ligands with high emission quantum yields (0.72-0.93) and high T(d)  (>400 °C) have been synthesized. Among the complexes, that shown in the figure has strong excimer emission attributed to the monomer triplet excited state with a localized structure. The application of this low band-gap material on single-dopant organic or polymer white-light-emitting diodes (WOLED) is highlighted.
