Outline of Final Research Achievements

We have approached to synthesize a porous metal complex showing superelasticity . In order to achieve it, we initially searched stress-induced transformation in single crystals of various low molecular-weight organic compounds,and investigated key molecular structures or crystal structures for exhibiting superelastic nature. As a result, we have found several low molecular weight organic compounds showing "ferroelasticity" which is a shear stress induced deformability of crystals similar to superelasticity but does not have spontaneous reverse deformation. We succeeded for the first time in elucidating the mechanism of ferroelastic deformation by observing the mechanical properties in addition to the microscopic structural changes and macroscopic crystal deformations. These structural knowledge obtained so far are useful for the synthesis of various of the superelastic materials and ferroelastic materials.
