How do I understand electrochemical interface at nanoscale?

ABOUT RESEARCH

　We have studied the characterization of adsorbed layers at electrochemical interface. Actually, construction and fabrication of characteristic nanoarchitectures by the self-assembly of organic molecules are a subject of significant interest. The ‘bottom-up’ strategy is an attractive and promising approach for the construction of nanoarchitectures and new functional nanomaterials. We have mainly focused two-dimensional molecular assembly and dynamics at solid-liquid electrochemical interface by using cyclic voltammetry (CV), electrochemical scanning tunneling microscopy (EC-STM), in situ FT-IR (surface-enhanced IRAS), and Raman spectroscopy.
　Recent our research interests are metal-complex adlayers and electrochemical sensors. For example, metalloporphyirns, fullerenes, polycyclic aromatic hydrocarbons (PAHs), self-assembled monolayers of thiols are target materials. We are also interested in ionic liquids (ILs) electrochemistry. ILs are expected to be promising solvents because ILs have excellent properties, such as high chemical and thermal stability, negligible vapor pressure, and a wide electrochemical potential window. We have investigated the electron transfer reaction of fullerenes thin films in various ILs.
