Sigma-hole造成的次级键作用在p区结构化学中有十分重要的作用。立足于此类相互作用的催化等应用也因此应运而生。此文简单地介绍一下此类相互作用。 Ref: ①Lim and Beer, Sigma-Hole Interactions in Anion Recog…
Named after the donor atom's group, the σ-hole interactions, halogen bonding, and chalcogen bonding with anionic species have found ground-breaking applications in anion supramolecular chemistry within the last decade. In this review, we feature key recent discoveries and advances across the whole ...

In this paper, we show computationally that significantly positive sigma-holes, and subsequent noncovalent interactions, can also occur for atoms of Group IV. This observation, together with analogous ones for the molecules (H3C)2SO, (H3C)2SO2 and Cl3PO, demonstrates a need to expand the ...

Crystal engineering based on sigma-hole interactions is an emerging approach for realization of new materials with higher complexity. Neutral inorganic clusters derived from 1,2-dicarba-closo-dodecaborane, substituted with -SeMe, -TeMe, and -I moieties on both skeletal carbon vertices are ...

Pnictogen bonding, arguably, is one of the least explored members of the young family of sigma-hole interactions, despite the tremendous advances that have been made in "unconventional" supramolecular chemistry across recent years. One of its well documented properties is that its strength is ...
