| Outline of Final Research Achievements |
The modern electronics based on solid state devices may undergo a paradigm shift to the molecular technology that underlies organic molecular electronic devices. We need new methodology to realize macroscopic functional dynamics by the nano-regulation of molecular organizations through the mesoscopic molecular assembly change. This study aimed at the development of electrochemical methods to control macroscopic large amplitude dynamics of organic molecules, extremely small amount of oil, and nanoparticles by nano-regulation on electrode surfaces, namely by potential changes.
The main research achievements are: (1) Potential dependent movements of oil droplets on a gold electrode surface were highly controlled by applying lower voltage than 1 Volt, (2) At a far negative potential commencing hydrogen evolution, emergence of a super-oil-repellant property was found for the first time, and (3) Molecular level mechanisms of two-dimensional faradaic phase transition were clarified.
