Paragraph 0072; 0074, (2018/10/19)
The invention provides a fluorenofluorene-containing compound and an organic electroluminescence device thereof and relates to the technical field of organic photoelectric materials. A fluorene-fluorene main body is connected with arylamine and a substituted or non-substituted fused imidazole derivative to obtain the fluorenofluorene-containing compound. The compound is a bipolar transmission material, is favorable for compounding holes and electrons in a luminescent layer, has good stability and luminescent efficiency, is simple in synthesis and easy to operate, can be applied to the organicelectroluminescence device to serve as a doping material of the luminescent layer, and can effectively solve the problems of low luminescent efficiency and short service life of a blue luminescent material in the organic electroluminescence device. The organic electroluminescence device provided by the invention has the advantages of high luminescent efficiency and long service life.
