The Mechanochemistry of Carboranes

Angewandte Chemie - International Edition, 2022
AbstractWe developed o‐carborane as a new mechanophore by showing that the o‐carborane cluster is the preferred scission site in chain‐centered polymers through ultrasonication mechanochemistry. Mechanistic studies are consistent with a predominately homolytic mechanism of chain scission.

Mechanochemistry of Pterodactylane

Journal of the American Chemical Society, 2023
Pterodactylane is a [4]-ladderane with substituents on the central rung. Comparing the mechanochemistry of the [4]-ladderane structure when pulled from the central rung versus the end rung revealed a striking difference in the threshold force of mechanoactivation: the threshold force is dramatically lowered from 1.9 nN when pulled on the end rung to 0 ...

Mechanochemistry of Cubane

Journal of the American Chemical Society, 2022
We report the mechanochemical reactivity of the highly strained pentacyclic hydrocarbon cubane. The mechanical reactivity of cubane is explored for three regioisomers with 1,2-, 1,3-, and 1,4-substituted pulling attachments. Whereas all compounds can be activated thermally, mechanical activation is observed via pulsed ultrasonication of cubane ...

Mechanochemistry of collagen

Acta Biomaterialia, 2023
The collagen molecular family is the result of nearly one billion years of evolution. It is a unique family of proteins, the majority of which provide general mechanical support to biological tissues. Fibril forming collagens are the most abundant collagens in vertebrate animals and are generally found in positions that resist tensile loading.

Mechanochemistry

2022
Although the history of mechanochemistry goes back centuries, with the rapid growth of articles about it, it is becoming clear that this once arcane discipline is becoming increasingly useful.

The mechanochemistry of cytogels

Physica D: Nonlinear Phenomena, 1984
We present a mechanochemical model for force generation by actomyosin cytogel. The model is built around the observation that calcium ions both solate actomyosin gels and stimulate active contraction of the gel. The model cytogel can mimic a variety of morphogenetic pattern-producing phenomena.

Experimental Polymer Mechanochemistry and its Interpretational Frameworks [PDF]

open access: yesChemPhysChem, 2017
Polymer mechanochemistry is an emerging field at the interface of chemistry, materials science, physics and engineering. It aims at understanding and exploiting unique reactivities of polymer chains confined to highly non-equilibrium stretched geometries
