| titleOfInvention | Bipolar blue-light phosphorescent main body material, preparation method thereof and organic electroluminescent device |
| abstract | The invention belongs to the field of organic electroluminescent materials and discloses a bipolar blue-light phosphorescent main body material, a preparation method thereof and an organic electroluminescent device. The material has a structural formula shown in descriptions. According to the bipolar blue-light phosphorescent main body material disclosed by the invention, acridine is a nitrogen heteroaromatic compound containing rich electrons and has a very good hole transport capability and a relatively high triplet energy level, and a phosphine sulfide group contains SP3 carbon and is a relatively good electron transport unit, so that the material simultaneously has a hole transport property and an electron transmission property, and the transporting of holes and electrons in a luminescent layer can be balanced; the material further has a relatively high triplet energy level, so that energy is effectively prevented from being transferred back to the main body material during luminescence, and thus, the luminescence efficiency is increased. |
