Tetradentate halogen bonding macrocyclic anion receptor inspired by the “Texas-sized” molecular box

An analogue of the tetracationic “Texas-sized” molecular box containing iodotriazole halogen bond-promoting subunits (“Ibox”) was prepared and found to recognize larger halides in organic media.

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.

Self-assemblies of anionic-unit-introduced anion-responsive π-electronic molecules

Carboxylate-appended anion-responsive π-electronic molecules provided anion-binding self-assemblies, as anionic supramolecular polymers, resulting in ion-pairing assemblies.

Bactericidal urea crown ethers target phosphatidylethanolamine membrane lipids

In this manuscript we report a small molecule that can selectively bind to the bacterial lipid phosphatidylethanolamine and consequently functions as an antibacterial agent against certain Gram-positive bacteria.

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.

The effect of solvent on the binding of anions and ion-pairs with a neutral [2]rotaxane

In this work we report the binding properties of rotaxane 1 towards a series of tetraalkylammonium salts of Cl, OCN and NO3 anions in acetone and a CHCl3/MeOH solvent mixture.

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.

Selective binding of anions by rigidified nanojars: sulfate vs. carbonate

By using nanojars as anion binding agents, selectivity for either carbonate or sulfate can be achieved upon rigidification of the nanojar outer-shell with tethers of varying lengths between pairs of pyrazole ligands.

Selective sensing of adenosine monophosphate (AMP) over adenosine diphosphate (ADP), adenosine triphosphate (ATP), and inorganic phosphates with zinc(II)-dipicolylamine-containing gold nanoparticles

Mixed monolayer-protected gold nanoparticles with surface-bound zinc(II) dipicolylamine units allow the selective detection of adenosine monophosphate in an aqueous solution.

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
