A colour-changing compound that can precisely indicate the ‘enantiomeric excess’ (ee) of chiral molecules could provide a convenient method to measure pharmaceutical purity. Many molecular systems in ...

Doubly stapled α-helix consisting only of achiral amino acids. Its one-handed form can be isolated because the interconversion between the right- and left-handed forms is almost completely suppressed.

Researchers report a new method for distinguishing between enantiomers, molecules that are mirror images of each other. The procedure, relevant for the pharmaceutical industry, involves the chemical ...

Cage-shaped molecule that changes from left-handed to right-handed when a metal ion enters its inner cavity. The conversion speed varies up to 1000 times depending on the size of the metal ion (K +, ...
