We are studying subjects in solid-state physical chemistry based on metal complexes or coordination compounds, in which our goal is directed to synergistically control the electronic and magnetic properties and behavior of molecular frameworks, and finally to create new soft molecular materials with unique phenomena. Techniques of crystal engineering or molecular self-assembly with metal complexes enable the creation of diverse molecular frameworks and supramolecular architectures. Many metal complexes have traits such as high redox activity, high charge-transfer activity between metal ions and ligands, and paramagnetism with a large anisotropy controllable by ligand fields around the chosen metal ion. We will be able to tune these characteristics and design “functional” and “dynamical” molecular frameworks as if they were simply constructed using Lego blocks. “Molecules” including metal complexes have the high design performance and flexibility in their type diversity, so it is our new challenge to manipulate on-demand electrons/spins on multi-dimensional frameworks constructed by metal complexes.
Enjoy our research and welcome us to the leading laboratory for solid-state metal-complex chemistry.
What is “KINKEN”? What is IMR? Probably, most of chemists do not know about “KINKEN, IMR.” IMR is one of the leaders in the world in a wide field of research on solid-state materials and their properties, such as metallic materials, oxides, ceramics, semiconductor materials, hydrogen-adsorbing materials, nuclear materials, biomaterials, and unique functional materials for next-generation electronic materials such as spintronic materials, strongly correlated materials, optical device materials, and organic materials. IMR is always transmitting information on unique materials, technologies, and science to the rest of the world based on our knowledge and skills obtained by merging basic and applied sciences, and science and engineering.

The Graduate School of Science and Faculty of Science at Tohoku University has a program for international graduate students, IGPAS (International Graduate Program for Advanced Science), where candidates choose either Master’s Program (5 years = 2M+3D) or Doctoral Program (3 years). Note that the students have a chance to apply for financial support from the Japanese government (MEXT) scholarship. The application period will be given in November every year; therefore, if you wish to have this program, contact us as soon as possible.
See detail on the web site:

Of course, we always welcome you as self-supporting international graduate students.
IMR, as a world-class Center Of Excellence (COE) for Material Science, has provided open (management/ operation) for researchers in Japan and all around the world. By providing advanced technology research equipment in large and unique facilities to university/research organization researchers, has contributed to promotion of Material Science research and development of research communities in Japan. As a COE in material research, this institute has achieved a social task by widely publishing the results of collaboration research. In recent years, much effort has been put into international collaboration research, due to the globalization of research in this field. To take this collaboration one step further and to strength the international presence as a world-class COE, this institute is launching international collaboration research program.
If you wish to do a collaboration with our group, please contact me (Prof. Miyasaka, E-mail: miyasaka@imr.tohoku.ac.jp)
