Since the start of this millennium, remarkable progress in the binding and sensing of anions
has been taking place, driven in part by discoveries in the use of hydrogen bonding, as well …

Squaramides are remarkable four-membered ring systems derived from squaric acid that
are able to form up to four hydrogen bonds. A high affinity for hydrogen bonding is driven …

In this minireview, squaramides are presented from their roots as artificial anion receptors in
molecular recognition studies to their recent advances as powerful bifunctional hydrogen …

The field of anion coordination chemistry has received more and more attention in recent
years. A large number of articles, from the initial anion recognition to various applications …

This review covers recent advances in the use of the squaramide moiety in chemical
research. We focus on the varied applications of squaramides under the broad headings of …

The transmembrane transport of anions, particularly chloride and bicarbonate, is an
important biological process that is normally regulated by transmembrane ion channels. A …

The two-volume Encyclopedia of Supramolecular Chemistry offers authoritative, centralized
information on a rapidly expanding interdisciplinary field. User-friendly and high-quality …

This review article illustrates the contribution of amide based receptors to the development
of anion complexing agents. Amides are incorporated into a wide variety of systems that can …

Bifunctional squaramides as a branch of organo‐catalysts showed powerful strategies in the
art of asymmetric synthesis, and they have been proved to be highly efficient and versatile …

The interaction of a neutral squaramide‐based receptor, equipped with two 4‐nitrophenyl
substituents (Rsq), with halides and oxoanions has been studied in MeCN. UV/Vis and 1H …
