Spirofluorene derivatives, preparation method thereof, and organic light-emitting device |
| abstract |
The invention relates to a spirofluorene derivative, a preparation method thereof and an organic light-emitting device, belonging to the technical field of electroluminescent materials. Described spirofluorene derivatives, its structural formula is as follows: Wherein, R is a substituted or unsubstituted C 1 -C 60 alkyl group, a substituted or unsubstituted C 6 -C 60 aryl group, a substituted or unsubstituted C 5 -C 60 condensed ring group, a substituted or unsubstituted A substituted C 5 -C 60 heterocyclic group. The present invention also provides a method for preparing spirofluorene derivatives. The reactants are subjected to Suzuki reaction to obtain spirofluorene derivatives. The organic light-emitting device prepared by using the spirofluorene derivative provided by the invention has the advantages of high luminous efficiency and long service life. The preparation method of spirofluorene derivatives provided by the invention has easy-to-obtain raw materials, simple preparation method and easy industrialization. |
