What are the interesting and peculiar
points of organic materials in comparison with inorganic ones?

In the high school time, I enjoyed chemical experiments. My favorite was beautiful color of transition metals and my questions were why ruby is red and sapphire is blue. My major in the University was chemistry and the research of the functional organic materials has been started. Fortunately, I discovered the new organic superconductor with the world record of the transition temperature. The discovery was beyond my expectation and the reply of nature to my question.

My dream is to discover the novel functionalities in order to expand the possibilities of organic materials. Recently, we found the metallic state of the single-component of purely organic materials, even though organic materials were originally insulators.

Why do not you join our group and have your enjoyable experience to find new functional materials with us?

Introduction of the study

Introduction of the study

The syntheses and structural and physical properties for molecular functional materials such as molecular (super)conductors, magnets, and dielectrics have been studied. The attractive points of molecular materials are 1) that there is a variety of materials since around 70 million kinds of molecules have been synthesized so far and new molecules are being designed and synthesized, 2) that molecules and intermolecular interactions are designable and controllable, 3) that large response of external pressure and electron-phonon coupling are observed due to softness of molecules, and 4) that large Coulomb interactions (electron correlation) reflect the magnetism as well as conductivity in molecular conductors.

Our group has investigated the curious molecular functional materials based upon charge, lattice, spin, and molecular degree of freedom by changing physical parameters with designed molecules. Recently, we found new organic superconductors, in which the superconducting state is competitive to the charge ordered state owing to the electron correlation and the bending and stretching of designed molecules. (Figure) Moreover, the metallic state of single-component purely organic conductor by using the hydrogen bond is successfully discovered. These basic researches are related to seeds of applications such as the new type of the organic electronics.

Even though Prof. Mori is in her busy time, she responds to the students’ questions quickly and kindly. All members in our lab are doing their own jobs extensively in the working time and have a relaxed and enjoyable chatting time in the lunch time together.

Why do not you visit our lab if you are interested in the development of new functional materials? It is very fun to discover new interesting materials. These basic researches are supposed to be related to the unexpected new applications.
