| titleOfInvention |
Spiroaromatic hydrocarbon compound, preparation method thereof and organic electroluminescent device |
| abstract |
The invention discloses a spiro aromatic hydrocarbon compound and a preparation method thereof. The spiro aromatic hydrocarbon compound is prepared by using a commercial precursor material 3-bromo-9,9'-spirobis[fluorene] or 3,6- Dibromo-9,9'-spirobis[fluorene], synthesized by one-step reaction. The invention also discloses an organic electroluminescence device using the spiro aromatic hydrocarbon compound as a host material. The spiro aromatic hydrocarbon compound of the present invention has good device performance when applied to red/green/blue OLED, simplifies the structure of the white light organic light emitting diode device, and reduces the industrial production cost. |
