◼️ Overview of Research

Molecular metal compounds, which contain transition-metals as their centers, so called “metal complexes,” display diverse properties depending on their central metals, supporting ligands, bonding situation, and geometries.  We are studying about 1) metal complexes featuring multiple bonds between transition-metals and heavier main group elements (e.g. Group 13, 14, 15 elements), 2) metal complexes supported by multi-dentate chelate ligands, 3) polyoxometalates, and 3) metal complexes coordinated by Li+ ion encapsulated C60 fullerene, as main targets.  We are trying to synthesize metal complexes having new types of bonds and structures, and clarify their properties, reactivities, and electronic properties. Through these researches, we are aiming at finding new metal complexes that act as high-performance catalysts and also new functional compounds that show unprecedented electronic properties.
