Versuchsvorschrift

Similarly, monomer 2 is prepared from 3-(2-bromoethoxy)-4-methylthiophene (compound 4) and 1-methylimidazole (Aldrich Co.) (see Scheme 2). Compound 4 is prepared according to the procedure developed by Leclerc et al. (Faïd, K.; Leclerc, M. J. Chem. Soc., Chem. Commun., 2761, (1996)). The quaternization reaction between 1-methylimidazole and compound 4, provides the desired monomer imidazolium salt 2. (Lucas, P.; Mehdi, N. E.; Ho, H. A.; Belanger, D.; Breau, L. Synthesis, 9, 1253, (2000)).
