| Research Abstract |
In the present study, we focused on electrochemistry of ionic liquids to understand adsorption of anions and cations on Au electrode surface at nano-scale level. The influence of the alkyl chain length of the bis(trifluoromethylsulfonyl) imide-based ionic liquids alkyl-methylimidazolium, cation on the potential window was investigated with low-index Au single crystal electrodes by cyclic voltammetry. The potential window of the electrical double-layer region was found to depend on the crystallographic orientation of Au, which indicated a difference in the strength of cation adsorption on the Au substrate. EC-STM revealed that molecular adlayers of phthalocyanine and polycyclic aromatic hydrocarbons on Au(111) with clear molecular resolutions.
