  • Publication number: 20200354391
    Abstract: Disclosed is an organic light-emitting material including a 3-deuterium-substituted isoquinoline ligand. The organic light-emitting material is a metal complex including a 3-deuterium-substituted isoquinoline ligand and an acetylacetonate ligand, which can be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These novel complexes can effectively prolong device lifetime. Further disclosed is an electroluminescent device including the metal complex and a compound formulation.

  • Publication number: 20200358011
    Abstract: An organic light-emitting material contains a 6-silyl-substituted isoquinoline ligand. The organic light-emitting material is a metal complex containing a 6-silyl-substituted isoquinoline ligand and may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These new complexes can provide redder and saturated emission and meanwhile demonstrate a significantly improved lifetime and efficient and excellent device performance. Further disclosed are an electroluminescent device and a compound formulation including the metal complex.
