| Popis: | Five ferrocene alkymethylimidazolium cations 1a&ndash 1d and 2 with different alkyl spacer lengths were reinvestigated using voltammetry and density functional theory (DFT) calculations. The voltammetric responses of ligand 2 toward various anions are described in detail. An interesting and unprecedented finding from both experimental and theoretical studies is that coupled electron and intramolecular anion (F&minus ) transfer may be present in these molecules. In addition, it was also observed that, in these studied molecules, the electrostatic attraction interaction toward F&minus would effectively vanish beyond 1 nm, which was previously reported only for cations. |
