Reshaping Aromaticity and Chirality with Dynamic Bonds.

Researchers at the University of York have discovered that dynamic bonds can reshape our understanding of key chemical concepts, including aromaticity and chirality. They have synthesised a polycyclic molecule whose aromaticity can be switched on and off, as well as a carbon cage where chiral carbon atoms interconvert without breaking bonds at the stereocentre. These new concepts could one day underpin new applications for dynamic molecular materials.
