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 …

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 …

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 …

Thioureas represent the dominant platform for hydrogen bond promoted asymmetric
catalysts. A large number of reactions, reported in scores of publications, have been …

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

Ammonium ions are ubiquitous in chemistry and molecular biology. Considerable efforts
have been undertaken to develop synthetic receptors for their selective molecular …

We report here a small library of a new type of acyclic squaramide receptors (L1–L5) as
selective ionophores for the detection of ketoprofen and naproxen anions (KF–and NS …

Bisthiocarbonohydrazones are found to be a class of sensitive, selective, ratiometric, and
colorimetric chemosensors for anions such as fluoride (F−) or acetate (Ac−). The …

Unique hydrogen bonds of the 9-H of anthracene moieties in hosts 1 and 2 with fluoride and
pyrophosphate ions were observed on the basis of the 1H NMR experiments. Furthermore …
