-
Paragraph 0059; 0061, (2018/11/22)
The invention provides a benzfluorene derivative and an organic light-emitting device containing the same, and relates to the technical field of organic optoelectronic materials. According to the benzfluorene derivative and the organic light-emitting device containing the same, by connecting a substituted or unsubstituted aromatic-ring condensed imidazole derivative and aromatic-ring condensed oxazole derivative onto a benzfluorene main body, the benzfluorene derivative is obtained. The benzfluorene derivative has certain electron transportation capability, is beneficial to compounding of holes and electrons in a light-emitting layer and has good stability and high light-emitting efficiency, synthesis is simple and easy to operate, and the benzfluorene derivative can be applied to the organic light-emitting device as a light-emitting layer doped material, so that the problems can be effectively solved that in the organic light-emitting device, a blue light-emitting material is low in light-emitting efficiency and short in service life, and the organic light-emitting device containing the same has the advantages of being high in light-emitting efficiency and long in service life.
