The invention discloses a series of polymerizable novel organic monomers 3,3,-di(dialkoxyphosphonyl)-4,4,-dihalogenated diphenylsulfone and a preparation method thereof. The preparation method comprises the following steps: mixing 3,3,-dibromo-4,4,-dihalogenated diphenylsulfone with phosphite triester according to a molar ratio of 1: (6.0-8.0), reacting in light under the nitrogen protection, after the reaction is finished, performing reduced pressure distillation, and performing chromatographic column chromatography to obtain the monomers. The novel organic monomers have polymerization reaction with other monomers in the presence of medium-strong alkali in a high-boiling-point non-protonic organic solvent to obtain a novel polymer containing phosphonate groups; the polymer is acidified and neutralized to obtain a novel high-molecular material containing phosphonic acid groups and phosphonate groups; the material is relatively good in nanofiltration/reverse osmosis desalination performance and proton conducti
