The invention provides a compound containing diphenyl sulfone as a skeleton and a preparation method and application thereof, and the name of the compound is 10-(4-((3, 5-bis (9H-carbazole-9-yl) phenyl) sulfonyl) phenyl)-9, 9-dimethyl-9, 10-dihydroacridine. The preparation method comprises the following steps: carrying out a carbon-carbon coupling reaction on 9, 9'-(5-bromo-1, 3-phenylene) bis (9H-carbazole) and 4-chloro-1, 2-dimercaptobenzene to synthesize 9, 9'-(5-((4-chlorphenyl) sulfo)-1, 3-phenylene) bis (9H-carbazole); oxidizing the 9, 9'-(5-((4-chlorphenyl) sulfo)-1, 3-phenylene) bis (9H-carbazole) by using m-chloroperoxybenzoic acid to obtain 9, 9'-(5-((4-chlorphenyl) sulfonyl)-1, 3-phenylene) bis (9H-carbazole); finally, enabling the 9'-(5-((4-chlorphenyl) sulfonyl)-1, 3-phenylene) bis (9H-carbazole) and 9, 10-dihydro-9, 9-dimethyl acridine to be subjected to a Ullmann coupling reaction, and obtaining the target compound. The compound has excellent thermal stability, electrochemical stability, charge transfer performance and luminescence performance, and can be used as a blue organic electroluminescent material.
