The invention relates to a monomer (
6, 14
) carrying an imidazole-type heterocycle (
3
). According to the invention, the chemical structure of said monomer (
6, 14
) comprises at least one unit of formula (I) wherein R1 comprises an alkenyl grouping and R2 comprises a grouping for protecting one of the nitrogen atoms of the heterocycle. The invention also relates to a monomer carrying a benzimidazole-type heterocycle, and to protected polymers obtained from said monomers, deprotected polymers produced by the protected polymers, a proton exchange membrane based on deprotected polymers, and a fuel cell provided with said membrane. Furthermore, the invention relates to methods for producing the above-mentioned monomers and polymers.

The title compounds were synthesized in quantitative yields by interacting cl-hydroxyalkyl ferrocenes with polyfluoroalkyl benzimidazoles in an aqueous-organic medium in the presence of HBF4. The resulting diastereomers and enantiomers were resolved using HPLC on silica bonded chiral stationary phases based on chiral cyclodextrins and cyclic antibiotics. The X-ray determination of molecular and crystal structure of 1-ferrocenylmethyl-2-(trifluoromethoxyfluoromethyl)benzimidazole (1) was carried out. (C) 1999 Elsevier Science S.A. All rights reserved.
