| titleOfInvention |
Bipolar blue light phosphorescent material, preparation method and organic electroluminescent device thereof |
| abstract |
Belonging to the field of organic semiconductor materials, the invention discloses a bipolar blue light phosphorescent material, a preparation method and an organic electroluminescent device thereof. The material has a structural formula shown as the specification. The bipolar blue light phosphorescent material provided by the invention has hole transport properties and electron transport properties, and enables balance transport of holes and electrons in a luminescent layer. Also, the material has a high triplet state energy level, and can effectively prevent back transmission of energy to the host material in a luminescence process, thus greatly improving the luminescence efficiency. |
