CONJUGATED COMPOUND CONTAINING DIPHENYL SULFONE PHENYL STRUCTURE, METHOD FOR PREPARING SAME, AND APPLICATION THEREOF

摘要

A conjugated compound containing a diphenyl sulfone phenyl structure, a method for preparing same, and use for fabricating a light emitting layer or an electronic transmission layer of an organic electroluminescent diode. The compound has a chemical structure of one of the following general formulas: Formula A , Formula B . In the present invention, multiple conjugated aromatic units and halogen-substituted diphenyl sulfone phenyl are selected, and Suzuki coupling, Buchwald-Hartwig coupling or copper catalytic halogenated aromatic hydrocarbon amination reaction is performed to obtain a conjugated compound containing a diphenyl sulfone phenyl structure. A novel compound prepared by the present invention has fluorescence and certain conductivity, and therefore is applicable to fabrication of a light emitting layer or an electronic transmission layer of an organic electroluminescent diode.
