The invention belongs to the technical field of macromolecular materials and synthesis thereof and particularly relates to a tetraamino monomer and a preparation method and an application thereof. The invention provides 4, 4'-di[3, 5-di(2-trifluoromethyl-4-amino phenoxyl) phenoxy] diphenyl sulfone and a preparation method and an application thereof. The preparation method comprises the following steps: carrying out polycondensation on 4, 4'-di[3, 5-di(2-trifluoromethyl-4-amino phenoxyl) phenoxy] diphenyl sulfone and dianhydride to prepare acid anhydride or amino capped hyperbranched polyimide; and carrying out reaction on 4, 4'-di[3, 5-di(2-trifluoromethyl-4-amino phenoxyl) phenoxy] diphenyl sulfone, dianhydride, 3, 5-bistrifluoromethyl aniline and 3-alkynyl aniline to obtain 3, 5-bistrifluoromethyl aniline and 3-alkynyl aniline jointly capped hyperbranched polyimide. The material has high thermal stability, excellent solubleness and good optical performance and has a broad application prospect in the optical field.
