Abstract: An estrone imprinted polyimide nanofiber mat was prepared by using an electrospinning method. The diamine monomer-template complex was synthesized by the reaction of the diamine monomer having an isocyanate group and estrone (template) having a phenol moiety, in which the template was attached to the monomer via a thermally reversible urethane bond. A poly(amic acid) was synthesized by polymerization of the diamines (1:19 mole ratio of the diamine monomer-template complex to 4,4'-oxydianiline) and pyromellitic dianhydride in N,N-dimethylformamide and the reaction solution was used for electrospinning. The poly(amic acid) fibers were thermally imidized and then heated in 1,4-dioxane in the presence of water to remove the template molecules. The imprinted polyimide nanofibers showed the specific recognition ability and fast kinetic adsorption for estrone
