研究の背景 Background


Hydrogen is a protean element, which holds the key to drastically changing the functionalities of a wide range of materials. It is also attracting attention as a next-generation energy source, and the establishment of scientific basis for fully controlling hydrogen in materials will lead to the realization of new scientific fields and a new social infrastructure. Molecular solids are an excellent material group in terms of their rich designability of molecular/assembled structures, flexibility, and environmental compatibility; therefore, hydrogen-functional molecular solids have the potential to become new materials that can realize a sustainable society in the next generation.

研究の目標 Outcome


Hydrogen functionalities such as dielectric properties and anhydrous proton conductivity, and hydrogen–electron-coupled properties have been investigated for molecular solids with hydrogen-bonding ability and dynamics of protons. Utilizing the availability of single crystals, developments of new functionalities of new materials, and pursuing the underlying scientific principles are challenged by consistently performing molecular design, crystallization, structural analysis, single-crystal measurements, and first-principles calculations.
