Insights for designing mechanochromic spiropyrans from first principles dynamics and minimum energy pathways
… This may allow the development of novel stress-responsive materials. In this work, we use first principles dynamics and constrained optimization approaches to investigate the mechanochemical activity of a spiropyran molecule. When a particular bond is broken, the spiropyran changes color. …

Chemomechanics with a molecular force probe
… an emerging area at the interface of chemistry, materials science, physics, and biology that aims at quantitative understanding of reaction dynamics in multiscale phenomena. These are characterized by correlated directional motion at multiple length scales—from molecular to macroscopic. To …

Controlling and Exploiting Spiropyran-based Mechanochromism
<p>When mechanical force is applied to synthetic materials, polymer chains become</p><p>highly strained, leading to bond scission and ultimately material failure. Over the last</p><p>decade or so, work in the field of polymer mechanochemistry has coupled this tension to</p><p>desired covalent …
