Organoelement Chemistry Institute for Chemical Research, Kyoto University



We aim to synthesize new molecules, explore the unknown properties of the molecules, and develop the functions that emerge when these molecules are assembled. We aim to develop "Full-Spectrum Chemistry" that can contribute widely to science and technology. We will thoroughly pursue the possibilities of our original organic molecules.

Our strategy is as follows:

  • Precise molecular design using computational science
  • Organic synthesis incorporating state-of-the-art reactions
  • Development of novel skeletons utilizing the characteristics of heteroatoms
  • Structural analysis and spectroscopic characterization using a variety of instruments
  • Bottom-up synthesis of nanocarbon materials and substrate surface-assisted synthesis
  • Orientation control of organic molecules and their application to organic electronic devices
