Outline of Final Research Achievements

The development of new materials that exhibit reversible changes in physical properties in response to external stimuli has attracted significant attention for their potential applications in molecular devices. We aimed to synthesize dynamic metal complexes and clusters with superior magnetic, conducting and dielectric properties. We successfully obtained a Co10 single molecule magnet, an Fe42 high spin cluster, and a spin crossover conductor.
