Organic Light-Emitting Diodes Based on a Binuclear Platinum(II) Complex

Electroluminescent properties of an emissive binuclear platinum(II) complex have been studied. We fabricated organic light-emitting diodes based on Pt 2 (ppy) 2 (pyt) 2 (ppy = 2-phenylpyridine, pyt = pyridine-2-thiolate) phosphor, which exhibits an emission from a 3 MMLCT state based on a Pt-Pt inte...

Zusammenfassung:Electroluminescent properties of an emissive binuclear platinum(II) complex have been studied. We fabricated organic light-emitting diodes based on Pt 2 (ppy) 2 (pyt) 2 (ppy = 2-phenylpyridine, pyt = pyridine-2-thiolate) phosphor, which exhibits an emission from a 3 MMLCT state based on a Pt-Pt interaction. An electrophosphorescent device with a multilayer configuration of ITO/CuPc/NPB/Pt 2 (ppy) 2 (pyt) 2 /BAlq/Alq 3 /LiF/Al demonstrated red emission with Commission Internationale de L'Eclairage (CIE) coordinates of x =0.65, y =0.35, a maximum luminous efficiency of 1.8 cd/A (1.0 mA/cm 2 ), and an external quantum efficiency of 3.4%.
