Immobilization methods of lariat azacrown ether, containing oxyethylene spacer in the sidearm of crown ring, on the polymer matrix were studied. Crown ethers bound to polystyrene resins by oxyethylene spacer were obtained by the reaction of monoazacrown ether with 2-tosyloxyethoxy- or 2-(2-tosyloxyethoxy)ethoxy methylated polystyrene resins, derived from tosylation of 2-hydroxyethoxy- or 2-(2-hydroxyethoxy)ethoxymethylated polystyrene resins. This method presented a convenient route to immobilize various crown ether structure on polystyrene supports by poly(oxyethylene) spacers. Polymer supported simple crown ethers without oxygen donors in the spacer chain corresponding to the above lariat azacrowns were obtained by the reaction of crosslinked ω-bromoalkylated polystyrene resins with monoazacrown ether.
