• Multifunctional molecular-assemblies and hybrid organic - inorganic materials are examined from the viewpoint of structural freedom of organic molecules. The spin and electronic states of molecular-assemblies are designed in terms of electrical conductivity, magnetism, and ferroelectricity. Diverse molecular assemblies from single crystal, plastic crystal, liquid crystal, gel, to Langmuir-Blodgett film are our research targets, which were hybridized with inorganic gigantic clusters and metal nanoparticles. We are prepared to provide academic consultations to companies interested in our research.

• Monoatomic layered materials of Graphene, Transition metal sulfide nanosheet, nanocrystalline active materials, nanoparticles and nanoporous materials are investigated for realizing high capacity, high power, high safety and low cost energy storage devices as a post- Lithium ion battery. Advanced chemistry of functional materials and device processes for All solid state battery, Magnesium battery, fuel cells, supercapacitor and wearable batteries are investigated.

Academia – Industry collaboration with manufacturing companies of functional materials, batteries, and also smart grid, renewable energy, electrical power companies are encouraged for developments of advanced energy materials and post-Lithium ion battery.

• The main research subjects in this group are the experimental investigations of the organic molecular conductors. The characteristic properties of the organic materials are multiple flexibilities owing to the assemble structure of nanometer-size molecules. This flexbility comes up recently for developing the organic electronic devices. We explore the fundamental electronic properties of the organic molecular materials which have wide range of the ground states from superconductivity to insulating states resulting from the strongly correlated electrons in the molecular pi-orbital. Such features are closely connected to flexible and multiple degrees of freedom in charge, spin, molecular latticeand molecules themselves. We are actively studying on the interesting and important issues in the condensed matter physics from the viewpoints of the characteristic flexbility of the organic molecular materials. We are prepared to provide academic consultations to companies interested in our research.

• One of our major research focuses is to design the novel drug nanoparticles, so called “Nano-prodrugs”, and to apply them as anticancer drugs or eye drops with excellent delivery efficiency. Nano-prodrugs are constructed by synthetic prodrugs molecules which contains poorly water-soluble substituent. They could be fabricated to nanoparticles with 100 nm or less in size by our reprecipitation technique, which has been used to create organic nanomaterials. We are aiming at practical application of our Nano-prodrugs in the near future.

Our reprecipitation technique for fabricating organic nanomaterials is a versatile technique that can be applied to various organic molecules as well as drug compounds. We hope to conduct collaborative research with a willing company on controlling and evaluating properties of the organic nanoparticles.

• Flexible liquid crystal displays using thin plastic film substrates instead of glass substrates contained in current liquid crystal displays, are bendable, thin, lightweight, and do not crack, and generate new usage styles and human interfaces due to their excellent storability and portability. We have been researching the basic technologies for large-screen and high-quality flexible displays using functional organic materials including liquid crystal and polymer, so that anyone can enjoy fertile information services.

We hope to conduct collaborative research with a willing company in industry, for development and practical application of the advanced flexible display technologies.
