Abstract

Chalcogen bonds (ChBs) occur between molecules containing Lewis acidic chalcogen substituents and Lewis bases. Recently, ChB emerged as a pivotal interaction in solution-based applications such as anion recognition, anion transport and catalysis. However, before moving to applications, the involvement of ChB must be established in solution. In this Concept article, we provide a brief review of the currently available experimental investigations of ChB in solution.

The detection of the chalcogen bond (ChB) in solution is a prerequisite for its use in solution-based applications. The current analytical methods used to establish ChB in solution and to quantify its strength are highlighted in this Concept article.
