Five ferrocene alkymethylimidazolium cations ⁻ and with different alkyl spacer lengths were reinvestigated using voltammetry and density functional theory (DFT) calculations. The voltammetric responses of ligand 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) transfer may be present in these molecules. In addition, it was also observed that, in these studied molecules, the electrostatic attraction interaction toward F would effectively vanish beyond 1 nm, which was previously reported only for cations.
使用伏安法和密度泛函理论（DFT）计算重新研究了五个不同烷基间隔长度的二茂铁烷甲基咪唑𬭩阳离子 ⁻ 和 。详细描述了配体 对各种阴离子的伏安响应。实验和理论研究都得出了一个有趣且前所未有的发现，即这些分子中可能存在耦合电子和分子内阴离子（F）转移。此外，还观察到，在这些研究的分子中，静电吸引相互作用对 F 的有效作用范围超过 1nm 时会消失，这在以前仅报道过阳离子。
