The great potential of Halogen Bonding
(XB), namely any noncovalent
interaction involving halogens as
electron acceptors, in the design of
new and high-value functional materials
is now emerging clearly. This
Highlight will give a detailed overview
on the energetic and geometric
features of XB, showing how some of
them are quite constant in most of the
formed supramolecular complexes, while some others depend strictly on the nature of the
interacting partners. Then, several
specific examples of halogen-bonded
supramolecular architectures, whose
structural aspects as well as applications
in fields as diverse as enantiomers?
separation, crystal engineering,
liquid crystals, natural, and synthetic
receptors, will be fully described.
