Outline of Final Research Achievements

In the present study, we fabricated layered super structures using metal complex or charge transfer complex molecules, in order to observe interesting quantum effects such as long-range electron transport ability, higher electrical conduction and optical adsorption due to the super lower dimensional structures. First, we fabricated Ru complex multilayers using several metal cations. We found that the electron transport properties of the multilayers containing Fe cations exhibited increased electron transport. In addition to the Ru complex multilayer, we fabricated TTF-TCNQ thin film which can be expected a larger electrical conduction. We found that N,N-Dimethylformamide is effective to increase the electrical conduction. We obtained highly conducting TTF-TCNQ films with ca 60 S/cm by a simple casting technique using N,N-Dimethylformamide.
