项目摘要

In the present project, international cooperative research work was carried out through the visiting each other, whose total times was 25 times per two years.As concrete examples of the results, with Prof. R. L. McCreery group, we performed nano-analysis of the deposited materials on the electrode surfaces using Raman spectroscopy. Consequently, on the basis of the Raman observations, the deposition mechanism of the conducted solids was clarified in the reduction of TCNQ with metal cations. In addition, with Prof. R. G. Compton, nano-electroanalytical technique was established using micro-band electrodes array with channel flow voltammetry. It was found that this approach is very effective in the clarification of the mechanistic aspects of the electrode reactions as well as the detection of trace materials.With Prof. H. Kim, we examined nano-analysis using calix[4]arene derivatives as an ionophore for metal cations. The specific inclusion behavior of the two quinone derivatyives was clarified through the cooperative research using flow-electrolysis UV-vis and ESR measurements. Also, with Prof. Y. B. Shim, we examined the electrode reactions of benzoquinone derivatives on lipid modified electrodes. Stabilization of the electrogenerated anion radical in the nano-space onto the electrode surface was clarified, together with the effects of alkyl chain length of the lipids on it. With Prof. R. E. Sioda, theoretical aspects of a column electrolysis method were studied for the detection of trace materials. In addition, with Prof. Y. Bohari, to clarify the molecular aspects of the electron transfer reactions, the electrochemical behaviors of ferrocene derivatives were analyzed.

在本项目中，国际合作研究工作是通过相互访问来进行的，其总次数为每两年25次。L. McCreery组，我们进行了纳米分析的沉积材料的电极表面上使用拉曼光谱。因此，在拉曼观测的基础上，在金属阳离子还原TCNQ的导电固体的沉积机制澄清。此外，与R. G.康普顿，纳米电分析技术，建立了微带电极阵列与通道流动伏安法。结果表明，这种方法在阐明电极反应的机理方面以及痕量物质的检测方面是非常有效的。Kim，我们研究了使用杯[4]芳烃衍生物作为金属阳离子的离子载体的纳米分析。通过流动电解法、紫外可见光谱法和电子自旋共振法的协同研究，阐明了这两种醌衍生物的特殊包结行为。与Y教授B。Shim的基础上，研究了苯醌衍生物在脂质修饰电极上的电极反应。阐明了在纳米空间中电生成的阴离子自由基在电极表面的稳定性，以及脂质的烷基链长度对其的影响。E. Sioda，理论方面的柱电解法进行了研究，用于检测痕量物质。此外，与Y. Bohari，为了阐明电子转移反应的分子方面，对二茂铁衍生物的电化学行为进行了分析。
