| titleOfInvention | Bipolar phosphorescent host compound, preparation method and application, and electroluminescent device |
| abstract | The invention discloses a bipolar phosphorescent host compound, a preparation method and application thereof, and an electroluminescence device. The bipolar phosphorescent host compound is a bisbenzimidazole dicarbazole derivative, and its general structural formula is: ; Among them, when one of R1, R2 or R3 is When , the other two are H; when one of R1, R2 or R3 is , the other two are H. Described dibenzimidazole/dicarbazole derivatives all contain identical two (9-phenylcarbazole) groups, benzimidazole groups, adopt the 3-position of carbazole to pass through typical Suzuki reaction in the present invention The two groups of carbazole and benzimidazole are connected to maintain the bipolar transport performance of the two, and at the same time, due to the small reduction of its conjugated structure, its triplet energy level can still meet the needs of blue phosphorescent light-emitting devices. |
