New crown ether resins prepared by cationic template polymerization

Abstract The synthesis of several dibenzo‐18‐crown‐6 derivatives, and their acid catalyzed incorporation into crosslinked styrene and 4‐methoxystyrene based copolymers is described. Some of these reactions were carried out in the presence of chiral ammonium cations acting as non‐covalent templates. The polymers have been characterized by IR, and by 1 H and 13 C solution state and magic angle spinning NMR.
