Molecular amplifier makes purest chiral Möbius aromatic

Here is what it takes to make the most enantiopure Möbius aromatic molecule to date: a ring with 30 stereocentres, a set of linkers, zinc ion and its ligand. This chiral amplifier, chemists have discovered, can control a Möbius ring’s chirality, which could be useful for building molecular machines or switchable catalysts.
