| titleOfInvention | Amine derivatives of benzo 9,9'-spirobifluorene and its preparation method, application and device |
| abstract | The invention belongs to the technical field of photoelectric material application technology, and specifically relates to amine derivatives of benzo 9,9'-spirobifluorene and a preparation method, application and device thereof. The amine derivatives of benzo-9,9'-spirobifluorene provided by the present invention use 9-9-benzospirobifluorene and amines as basic structural units, and modify the amines to obtain an asymmetric structure. The compound provided by the invention has high glass transition temperature and good hole electron transport ability. When it is used as a hole transport material, it is different from the hole transport material commonly used in the prior art N,N'-diphenyl-N,N'-(1-naphthyl)-1,1'-biphenyl- Compared with traditional materials such as 4,4'-diamine (NPB) and other hole transport groups, the transport ability of holes and electrons has been significantly improved. In organic electroluminescent devices, this series of compounds and traditional hole transport The material has significantly improved glass transition temperature, current efficiency, power efficiency, external quantum efficiency and roll-off, and is an ideal hole transport material. |
