Atomic force microscopy probes mechanochemical kinetics
Exerting force in one direction increases Diels–Alder reactants’ sensitivity to pressure 1000 times
Experiments probing how force accelerates chemical reactions have provided new insights into mechanochemical kinetics. The findings by US-based scientists could inform the development of chemical manufacturing methods that are more sustainable and less wasteful than current approaches.
In mechanically activated organic chemistry, force drives the making and breaking of covalent bonds. This helps to minimise the waste and energy cost associated with organic synthesis because the reactions are run neat or with minimal solvent, and energy is provided through mechanical, rather than thermal, means.
