Claim:
1. A preparation method of a conjugated compound containing a bis(phenylsulfonyl)benzene structure, the conjugated compound comprising a chemical structure with one of structural general formulas as follows: in the formula A and the formula B, each benzene ring being covalently bonded with adjacent sulfonyl group, Ar unit or N(Ar) wherein the Ar unit has a conjugated structure and is one of aromatic rings constituted by vinylene group, ethynylene group and hydrogen and carbon atoms, aromatic heterocyclic rings constituted by carbon, nitrogen and hydrogen atoms, aromatic heterocyclic rings constituted by carbon , nitrogen, oxygen and hydrogen atoms, aromatic heterocyclic rings constituted by carbon, sulfur and hydrogen atoms, aromatic heterocyclic rings constituted by carbon, silicon and hydrogen atoms, aromatic heterocyclic rings constituted by carbon, nitrogen, sulfur and hydrogen atoms, aromatic heterocyclic rings constituted by carbon, silicon, sulfur and hydrogen atoms, and any combinations thereof; the preparation method comprising following steps: step 10, synthesizing a precursor of halogen-substituted bis(phenylsulfonyl)benzene; step 20, making the synthesized precursor of halogen-substituted bis(phenylsulfonyl)benzene to react with a borate ester compound of a Ar unit in the presence of catalyst in a manner of Suzuki coupling reaction, to thereby prepare the conjugated compound containing a bis(phenylsulfonyl)benzene structure, and a reaction equation is as follows: or, step 20′, making the synthesized precursor of halogen-substituted bis(phenylsulfonyl)benzene to react with a NH(Ar)
