From form to function: Mechanically flexible crystalline materials with controllable responses

 

 

SAŽETAK / ABSTRACT:

Mechanical flexibilty, an essential characteristic of most living systems, is rare among crystalline materials. Crystalline solids are in general brittle, and they tend to crack and/or break upon application of mechanical stress, especially if they are held together by intermolecular bonds that are of comparable strenght in all directions. Recently, however, there have been several reports of flexible organic crystals, and a few cases of 0-D metal-organic crystalline solids that can respond flexibly to an applied mechanical force. The very first paper on crystalline 1-D coordination polymers with mechanical flexibilty was published in 2018, wherein we also demonstrated that the extent of elasticity could be controlled by introducing small and controllable structural modifications, something that had not been accomplished before.

In order to fully understand and explain which conditions need to be met for crystalline coordination polymers to be adaptive and tunably flexible in response to external mechanical stimuli, we propose a combination of theory and experiment to systematically explore how specific structural features and intermolecular interactions impart mechanical properties in crystalline coordination polymers. The overarching goal of this interdisciplinary research effort at the interface of chemistry and materials science is to deliver robust and transferable guidelines for bottom-up design of coordination polymers with a priori determined flexibility.  Such materials would combine the best features of both soft and crystalline matter, by presenting tunable mobility whilst preserving a long-range order, and subsequently offer unique opportunities for materials science and engineering as they contain coordination polymers at their core, which can provide unprecedented access to a new generation of smart materials with tunable functionality.
