Bis(cholyl)-based chloride channels with oxalamide and hydrazide selectivity filters

Supramolecular bis(cholyl) ion channels with oxalamide and hydrazide as selectivity filters are reported. The hydrazide system showed superior chloride transport activity to oxalamide due to better anion recognition.

Hydrophilic and hydrophobic carboxamide pincers as anion hosts

“Bare bones” pyridine dicarboxamide and pyrazine tetracarboxamide pincer frameworks were used to probe supramolecular anion binding. The influence of hydrophilic vs. hydrophobic environments and the potential for synergistic interactions in the ditopic hosts were explored.

Amidosquaramides – a new anion binding motif with pH sensitive anion transport properties

We report a family of amidosquaramides with pKa values close to physiological pH. Intramolecular H-bonding affects anion binding leading to moderate Cl transmembrane transport at physiological pH, but under acidic conditions anion transport is effectively ‘switched on’.

Anion binding to a cationic europium(III) probe enables the first real-time assay of heparan sulfotransferase activity

We present a new luminescent europium(III)-based anion receptor that binds to PAP (adenosine-3′,5′-diphosphate). The increased emission intensity and lifetime of the receptor-PAP complex was used to develop the first real-time assay of heparan sulfotransferase activity.

Acridinone-based anion transporters

The acridinone 1,9-bis(thio)urea scaffold was repurposed for application in anion transport by appending a variety of electron-withdrawing groups to the peripheral phenyl moieties. High levels of activity were achieved which facilitated strictly electroneutral transport.

About this collection

Anion receptor chemistry is a rapidly developing field. The shift from fundamental research to the development of systems capable of functioning under real-world conditions drives the development of new catalysts, receptors and anion transporters. This collection, guest edited by Professors Katrina A. Jolliffe and Philip A. Gale (University of Sydney) showcases the latest advances in the Supramolecular Chemistry of Anions.

The scope of the collection includes all aspects related to the supramolecular chemistry of anions including the design of new anion receptors and their applications in anion sensing and transport processes, self-assembly, catalysis and selective extraction.

New articles will be added to the collection upon publication. Please return to this page frequently to see the collection grow
