Robust Phosphorescent Platinum(II) Complexes Containing Tetradentate O^N^C^N Ligands: Excimeric Excited State and Application in Organic White-Light-Emitting Diodes

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 Td (>400 °C) have been synthesized. Among the complexes, that shown in the figure has strong excimer emission attributed to th...

Description
Summary: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 Td (>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.
