Sigma (σ)-holes are electron-deficient regions that arise from the anisotropic distribution of
electron density on the atom of group 14 (tetrels), 15 (pnictogens), 16 (chalcogens), and 17 …

Macrocyclic structures are common synthetic targets in drug discovery,(1, 2) and therefore,
interest in their study is continuously increasing in this field.(3, 4) A classic example is …

Half a century after Schill and Lüttringhaus carried out the first directed synthesis of a [2]
catenane, a plethora of strategies now exist for the construction of molecular Hopf links …
