Anion recognition: synthetic receptors for anions and their application in sensors

Current Opinion in Chemical Biology, 1999
Important contributions to the field of anion sensing include electrochemical lipophilic uranyl salophene receptors incorporated into membranes that act as fluoride-selective potentiometric microsensors. A promising optical-based sensor, selective for cyclic AMP, involves a preorganized, molecularly imprinted polymer employing an intrinsic fluorophore.

Selective Recognition of Chloride Anion in Water

Organic Letters, 2020
A tricationic cage was synthesized via click chemistry. The cage has a preorganized cavity, which is surrounded by six relatively acidic C-H bonds. In organic solvent, the cage can recognize a variety of anions, among which the Cl- anion has the highest binding affinity due to size selectivity.

Solvent effects in anion recognition

Nature Reviews Chemistry
Anion recognition is pertinent to a range of environmental, medicinal and industrial applications. Recent progress in the field has relied on advances in synthetic host design to afford a broad range of potent recognition motifs and novel supramolecular structures capable of effective binding both in solution and at derived molecular films.

Sulfonamide carbazole receptors for anion recognition

Organic & Biomolecular Chemistry, 2011
Carbazole-based receptors functionalized with two sulfonamide groups have been synthesized and their properties as anion receptors have been evaluated. The receptor with bis(trifluoromethyl)aniline groups has shown a very high affinity for halide ions, especially remarkable as only two hydrogen bonds are formed in the complexes.

Anion Recognition by Neutral Macrocyclic Amides

Chemistry – A European Journal, 2005
AbstractAlthough amides often serve as anchoring groups in natural and synthetic anion receptors, the structure–affinity relationship studies of amide‐based macrocyclic receptors are still very limited. Therefore, we decided to investigate the influence of the size of the macroring on the strength and selectivity of anion binding by uncharged, amide ...

Dynamic Chemistry of Anion Recognition

2011
In the past 40 years, anion recognition by synthetic receptors has grown into a rich and vibrant research topic, developing into a distinct branch of Supramolecular Chemistry. Traditional anion receptors comprise organic scaffolds functionalized with complementary binding groups that are assembled by multistep organic synthesis.

Anion Recognition by a Silanediol-Based Receptor

Organic Letters, 2006
To explore the anion recognition ability of silanol hydroxy groups, a silanediol-based receptor 1 was prepared. Spectroscopic studies and X-ray crystallography revealed that the receptor exhibits the characteristic recognition of anions via two hydrogen bonds in chloroform.

Anion Recognition with Hydrogen‐Bonding Cyclodiphosphazanes

Chemistry – A European Journal, 2014
AbstractModular cyclodiphosph(V)azanes are synthesised and their affinity for chloride and actetate anions were compared to those of a bisaryl urea derivative (1). The diamidocyclodiphosph(V)azanes cis‐[{ArNHP(O)(μ‐tBu)}2] [Ar=Ph (2) and Ar=m‐(CF3)2Ph (3)] were synthesised by reaction of [{ClP(μ‐NtBu)}2] (4) with the respective anilines and subsequent ...
