Zusammenfassung: | The invention relates to a metal platinum complex and application thereof, when the metal platinum complex is used in an OLED (Organic Light Emitting Diode), especially in a blue light emission region, the metal platinum complex shows enhanced phosphorescence quantum yield, has good luminescence stability and high luminescence efficiency, and is suitable for serving as an emitter material in OLED application. The metal platinum complex provided by the invention can be used for obtaining the organic electroluminescent device with dark red phosphorescence electroluminescence and improved luminous efficiency, and the thermal stability of the luminescent device is good; the metal platinum complex provided by the invention regulates the photophysical properties of the metal platinum complex by regulating the structure of the ligand around the metal center and regulating the structure of the substituent on the ligand, has the advantages of narrow emission spectrum, high stability and high efficiency, and has wide a |
