Sažetak
Crystal engineering, since its very beginning some twenty years ago, has always been accompanied by profound interest in deeper understanding of intermolecular interactions and their subsequent use in deliberate formation of solid-state structures. Nowadays, it has reached such a point where we can successfully synthesize many of desired supramolecular connectivities and topologies, and grow crystalline solids of desired morphologies. These crystalline materials have for a long been believed to be brittle and inelastic, and that upon application of even relatively insignificant mechanical stress they readily crack and/or break. Recently, we have been witnessing a growing number of literature reports on mechanically responsive molecular crystals. They can flex elastically or plastically once external mechanical force is applied, and in all the examples, macroscopic behavior is likely a consequence of substantial anisotropy of intermolecular interactions. We have also recently observed flexible response to applied mechanical force for a class of acicular crystals of cadmium(II) coordination polymers, and results clearly demonstrated a need for deeper understanding of the explicit connection between form and function.
