Coordination Chemistry(Sakai Lab.)
Our group focuses on the realization of artificial photosynthetic molecular systems driving splitting of water (H2O) into H2 and O2 with use of solar energy (2H2O + 4hν → 2H2 + O2). With this aim, we have performed the design and synthesis of new molecular catalysts based on metal complexes that can promote both water reduction and water oxidation processes in high turnover frequencies with lower applied overpotentials. In order to realize the hydrogen society, development of such fast catalysts that can function with low overpotentials is crucial in minimizing the input energy to drive the overall water splitting processes. This approach is directed to expand the wavelength range used for solar water splitting to a wider range that extends to a lower energy region of solar spectrum. Thus, our group targets development of new molecular catalysts that drive both water oxidation and reduction with a lower applied overpotentials. For their wide spread practical use in the future, catalyst development using cheap abundant non-precious metals, such as Fe, Cu, Ni, Co, etc., is also targeted in these studies. Improvement in the photoinduced electron transfer processes that generate reducing and oxidizing equivalents from solar light absorption is also targeted.

Physical Coordination Chemistry(Ohba Lab.)
In the field of molecular materials, one of the important targets is the development of multi-functional material combining different properties and functions in a synergic way. Our group focuses on “coordination polymers” and “liposome” as a meso-scale platform for interlocking various functions and properties. The coordination polymers can provide functional space that consists of flexible, highly ordered and designable frameworks based on coordination bonds. The frameworks can be incorporated magnetic, electrical, optical and other properties, and also can adsorb molecules in the void of structure. The liposome, a spherical vesicle composed of a phospholipid bilayer, provides hierarchical composite with selectively incorporating different functional molecules into the hydrophilic inner water phase, hydrophobic lipid bilayer, and inner and outer surfaces. We are exploring advanced functions using such spaces with synergically linking plural different properties of components.

Physical Chemistry
Physical Chemistry of Soft-matters(Annaka Lab.)
We study the physical chemistry of soft condensed matter, which are easily deformable by external stresses, electric or magnetic fields, or even by thermal fluctuations. These materials typically possess structures which are much larger than atomic or molecular scales; the structure and dynamics at mesoscopic scales determine the physical properties of these materials. The goal of our research is to probe and understand this relationship. We study both synthetic and biological materials; our interests extend from fundamental physics to technological applications, from basic materials questions to specific biological problems.

Quantum Chemistry(Terasaki Lab.)
Atomic and molecular clusters offer a unique opportunity to elucidate how physical and chemical properties of a matter emerge as atoms and molecules associate together one by one. We are interested, for example, in how ferromagnetism emerges for iron, cobalt, and nickel among 3d transition metals, whereas other elements do not exhibit it. For another example, silver nanoparticles are known to show strong photoabsorption, so-called surface-plasmon resonance, which is technologically important in coupling light with materials. However, one does not know how this picture works for small particles less than 1 nm in diameter. Furthermore, clusters provide a model of catalysts to gain molecular-level insights into mechanism of chemical reactions. We tackle these problems in materials science with single-atom precision toward advanced nano-science and technology.

Various chemical and biological phenomena, such as molecular motor, proteins’ association, and electron transfer reaction, are studied on the basis of physics in our group. We are interested in medium effects, such as solvent effects. Those effects have been recognized to be minor. However, media often change the fates of solutes drastically. Actually, proteins work only under certain thermodynamic condition, and stabilities of colloidal dispersion systems are regulated by the system temperature, the salt concentration, and so on. And, those phenomena relate to the biological functions. We are basically interested in those phenomena. Our main tools are thermodynamics, statistical mechanics and numerical calculation by using computers, such as molecular simulations.

Structure-Function Biochemistry(Matsushima Lab.)
We have a strong interest in the molecular mechanisms of ligand-receptor interaction. There are many kinds of receptors on cell membranes, in the cytoplasm, in nuclei, etc. When a ligand binds to its specific receptor, it induces a conformational change in the receptor’s structure and the signal is then transmitted. Our main research targets are nuclear receptors which precisely regulate gene transcription. We focus on all nuclear receptors to elucidate their activation mechanisms comprehensively. Binding affinity is analyzed in vitro by radioligand binding assays, and transcription activity is measured by reporter gene assays using cultured cells. The other targets are pain-modulating receptors, which are G-protein couple receptors (GPCRs).
