The invention discloses a poly(aromatic (thio)ether sulfone material containing a phosphonate group. The preparation method comprises the following steps of mixing a monomer containing the phosphonate group and a bis(thio)phenol monomer (or two different bis(thio)phenol monomers) with a dihalide monomer at a certain ratio; in the presence of medium alkali, strong alkali and toluene, under the condition of heating to a certain temperature and in a high-boiling-point non-protonic solvent, firstly carrying out reflux and water diversion for a certain time and then evaporating toluene out, raising the reaction temperature and continuing the reaction for a certain time; after the reaction is completed, pouring the reaction liquid into deionized water, washing the obtained solids with deionized water for three times and carrying out vacuum drying to obtain a novel polymer containing the phosphonate group. The novel polymer containing the phosphonate group is hydrolyzed and neutralized to obtain a polymer containing
