It has been known that atomic force microscopy (AFM), in addition to providing topographic information, can be used to discriminate surface functional groups. Last year, we performed force curve measurements between electroactive ferrocene (Fc)-terminated self-assembled monolayers under independent control of the tip and sample potentials. These results have demonstrated that this AFM-based technique will be a powerful tool for investigating the structure of the ion pair between Fc^+ and counter anions. In this year, we performed force curve measurements under various electrolyte solutions, and succeeded in revealing the ion-pair structure in molecular scale.

众所周知，原子力显微镜(AFM)除了提供表面信息外，还可以用来区分表面官能团。去年，我们进行了电活性二茂铁(FC)自组装单分子膜之间的力曲线测量，分别控制针尖和样品的电位。这些结果表明，这种基于AFM的技术将是研究Fc~(2+)和反阴离子之间离子对结构的有力工具。在这一年里，我们在不同的电解液溶液中进行了力曲线测量，并成功地揭示了分子尺度上的离子对结构。
