| Research Abstract |
Main purpose of this project is to control the crystal forms in organic superconductors on the base of the information of the crystal growth, especially, its first stage. For the observation of the crystal growth in situ, we made the STM and AFM system by combining Nano Scope II with the electrochemical application. In this system, the application was changed to be able for the use in organic solvents. The facility of this system was confirmed by checking the image of long fatty acids adsorbed on the metal surface, but we could not succeed in getting the good image of crystals in the case of organic superconductors. Although the period of this project ends, we will continue the research and solve the problem for getting the good image of crystals.
In the point of the development of new organic superconductors, which is another global purpose of this project, we made two new findings. One finding is that even a molecule with a bulky group produce metallic salts. In these salts, a bulky group is found in vacancy in the crystal. This suggests us one method of introducing a functional group in organic superconductors. Another is that DHTTF derivatives also issue many metallic salts. In these donors, an double bond of TTF backbone is saturated, so pi system is narrow compared with corresponding TTF donors. We hope introducing a new guide for organic superconductors by researching the detail electronic and structural properties in these systems.
