Fluorine derivative and organic electroluminescence device thereof
-
Paragraph 0098-0099; 0101, (2019/02/04)
The invention provides a fluorine derivative and an organic electroluminescence device thereof and relates to the technical field of organic optoelectronic materials. Strong absorbing electron groupsare connected to a fluorine main body structure through double bonds, and one side or two sides are connected to a substituted or unsubstituted 4H-benzo carbazole structure to form the fluorine derivative which has good electron transmittability and hole transport ability, can improve the injection rate of carriers and the exciton recombination rate effectively, is good in thermal stability, goodin film forming property, simple to synthesize and easy to operate, can be applied to an organic light emitting device as a light emitting layer main body and/or a hole barrier layer, and can solve the problems that the organic light emitting device is unbalanced in carrier transfer, low in light emitting efficiency, short in service life and unstable in light and color effectively. The organic light emitting device has the advantages of being low in driving voltage, high in light emitting efficiency and long in service life.
