Outline of Final Research Achievements

Ferrous ion and a linear-shape bridging ligand were dissolved in two immiscible solvents respectively. The prepared two solutions were gently layered to form a liquid -liquid interface and progress the coordination reaction at the interface. A filmy material formed at the interface was characterized by cyclic voltammetry, UV-Vis spectroscopy and atomic force microscopy, and suggested that it is composed of metal complex wires. The SQUID measurement of the metal complex wires displayed the partial spin crossover behavior around 250 K, which suggested the possibility of the switching of the physical property triggered by the electronic state change due to the temperature.

Academic Significance and Societal Importance of the Research Achievements

外部からの刺激を与えることにより物性のスイッチングや調節を行うことが可能な金属錯体ワイヤは、物質としては１種類であるが複数の特性を持つ多機能分子材料になりうる。このような物質は分子エレクトロニクスの分野においてシステムの小型化などに寄与すると考えられる。また、１つの素子が複数の素子の役割を兼ねることも可能になり、システムの消費電力の低減に寄与できるものと期待される。
