Developments of Thermomechanical Properties of Soft Crystals

Research Outline

We develop the control methods for solid morphologies and physical properties of Soft Crystals based on superelasticity exhibited by organic solids (“organosuperelasticity”). A research of superelasticity has been limitedly developed so far as a unique physical property of special alloys known as shape-memory alloys (or superelastic alloys). Organosuperelasticity is a new solid property that appeared in chemistry, and it has reached at a new stage where a research of superelasticity can be developed by chemical techniques. In this research, we aim at (1) developing synthetic and formation methods of superelastic organic crystals, (2) deepening and expanding evaluation methods of the physical properties, and (3) developing modulatable optical properties coupled with superelasticity.
