This research group uses the power of metals to create new reactions and nanomaterials.
AboutAbout the lab
Creating new molecules and materials guided by organometallic chemistry
The Organometallic and Materials Chemistry Group studies the development of new catalysts and reagents and the precise synthesis of stable metal nanomaterials, based on organometallic chemistry.
Organometallic chemistry combines the properties of organic molecules and metallic elements, and holds the potential to create new functions.
The group is a satellite lab of Prof. Crudden of Queen's University in Canada. It has many researchers from overseas, and members often give presentations and hold discussions in English.
It belongs to the Institute of Transformative Bio-Molecules (ITbM) and also carries out joint research with biology research groups.
Key terms
- Organometallic chemistry
- Chemistry that deals with compounds in which carbon is directly bonded to a metal. It is used to develop new catalysts and reactions
- Reagent
- A substance added to bring about a desired chemical reaction. Unlike a catalyst, it is itself changed during the reaction
- Nanocluster
- A cluster of a few to several hundred metal atoms, with a size on the order of a nanometer

ResearchResearch themes
Based on organometallic chemistry, which combines the properties of organic molecules and metallic elements, the group develops new catalysts and reagents for molecular transformations and aims for the precise synthesis of stable metal nanomaterials. Its work covers the transformation of organosulfur compounds, the creation of gold nanomaterials, and the activation of molecules using light.
*Illustrative imageTransforming Organosulfur Compounds
Focusing on sulfones among organosulfur compounds, the group develops metal catalysts and organometallic reagents. It has developed synthetic methods for various arylmethane derivatives, aiming to establish a way to transform the unreactive carbon–sulfonyl bond and attach functional groups sequentially on an sp3 carbon.
*Illustrative imageStable Gold Nanomaterials with Carbene Ligands
Using N-heterocyclic carbenes (NHCs), which bind strongly to metals, as ligands, the group synthesizes stable gold nanoparticles and gold nanoclusters. In parallel, it studies applications of these nanomaterials as catalysts and luminescent materials.
*Illustrative imageActivating Molecular Bonds with Light
Light makes it possible to drive reactions that heating cannot, and to control molecular activation by where and when it is applied. The group is pioneering new light-driven molecular transformations and, together with biology research groups, aims to apply them to molecular tools that help elucidate biological phenomena.
