| titleOfInvention | A kind of compound with benzo[1,2-b:5,4-b'] dibenzofuran as core and application thereof |
| abstract | The invention discloses a compound with benzo[1,2-b:5,4-b']dibenzofuran as the core and application thereof. The compound of the present invention contains benzo[1,2-b:5,4-b']dibenzofuran structure, has strong rigidity, and connects five-membered cyclic or six-membered cyclic or seven-membered cyclic It has the characteristics of not easy to crystallize between molecules, not easy to aggregate, and has good film-forming properties; the compound of the present invention has different electron donating ability due to the branched structure, so the HOMO energy level of the material is different, and it can be used as different functional layer materials In addition, the compound of the present invention has a higher triplet energy level, which can effectively block energy loss and facilitate energy transfer. Therefore, after the compound of the present invention is applied to an OLED device as an organic electroluminescence functional layer material, the device efficiency and lifetime are greatly improved. |
