Abstract

<p>Superelasticity is a kind of diffusion-less plastic deformation showing spontaneous shape recovery. The unique mechanical property enables so-called shape-memory alloys to be used in practical applications such as a catheter, clothes, and sensors. Superelasticity had been considered as a mechanical property of a special kind of alloys since its discovery in Au-Cd alloy in 1932. Despite the conventional thinking, we discovered superelasticity in an organic crystal, named “organosuperelasticity”, in 2014. Following studies on deformability of organic crystals revealed that superelasticity and ferroelasticity-diffusion-less plastic deformation showing spontaneous strain-are more common than previously thought. Herein we show examples of organosuperelastic and organoferroelastic materials. Another kind of plastic deformability, superplasticity, which enables organic crystals deform over hundreds of percent in retaining crystal integrity will be also described.</p>
