Abstract: Platinum (II) complexes (“Pt(II) complexes”) that can emit in the red and/or deep red regions and methods of making and using thereof are described. These Pt(II) complexes can have dinuclearity with close Pt—Pt contact and close interplanar distance, allowing for high emission quantum yield, such as >50%, short emission lifetime, such as 9000 h for a red OLED.
