About Us

One of the exciting features of material science is its diversity. The unlimited combinations, connecting modes, and arrangements of elements enable a wide variety of structures and functions. Among several molecular materials, our group is focusing on molecules with open-shell electronic states, such as organic radicals and magnetic metal complexes. The unpaired electrons in such molecular materials are expected to produce exotic physical properties that are not realized by conventional closed-shell molecules or inorganic materials. We aim to develop novel photonic, magnetic, and electronic functions based on these open-shell molecules to provide breakthrough and innovations in material science. The road to discover something new is neither straight nor flat; we sometimes face to unexpected difficulties and problems in our research. By overcoming these, we can reach truly stirring findings that have never been disclosed. Let's enjoy the diversity of material science and find something impressive in natural science with us!
