A Maze of Crystal Adaptability

Mechanical adaptability to external stimuli is a highly desired property of crystalline solids as it enables their potential usages in a variety of emerging technologies. Although most of synthetic crystalline materials are largely incapable of dynamic responsiveness upon exposure to an external mechanical stimulus, relatively recently it has been demonstrated that those materials, under certain circumstances, may respond flexibly to external stimuli while still maintaining their integrity. However, to be able to implement mechanically responsive materials in smart devices, a control of their behavior with high accuracy is required. Crystalline coordination polymers, in particular 1-D ones, emerged as ideal model systems for exploring structural background and underlying principles that lead to targeted flexible responsiveness of crystalline materials. Moreover, they yielded a remarkable spectrum of extraordinary mechanical responses which were further explored via a number of advanced and custom-designed experimental methods, and in turn correlated with a variety of structural and energetic features.[2-5] Some of these properties, which will be presented in this contribution, reveal a striking resemblance of crystalline solids to soft materials, while a control of those provide additional advantages.
