Pyrazole Complexes as Anion Receptors

Chemistry – A European Journal, 2006
AbstractThe behavior of the receptors [Re(CO)3(Hdmpz)3]BAr′4 (Hdmpz=3,5‐dimethylpyrazole) (1) and [Re(CO)3(HtBupz)3]BAr′4 (HtBupz=3(5)‐tert‐butylpyrazole) (2; Ar′=3,5‐bis(trifluoromethyl)phenyl) toward the anions fluoride, chloride, bromide, iodide, hydrogensulfate, dihydrogenphosphate, nitrate, and perrhenate was studied in CD3CN solution.

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.

Metal–salophen-based receptors for anions

Chemical Society Reviews, 2010
In this critical review the use of metal-salophen complexes as anion receptors is discussed with an emphasis on the supramolecular control of selectivity derived by the presence of additional interaction sites on the ligand skeleton. Some examples of application in sensing are also reported (112 references).

From Anion Receptors to Transporters

Accounts of Chemical Research, 2011
Cystic fibrosis is the most well-known of a variety of diseases termed channelopathies, in which the regulation of ion transport across cell membranes is so disrupted that the threshold of a pathology is passed. The human toll exacted by these diseases has led a number of research groups, including our own, to create compounds that mediate ion ...

Amidocrownophanes as Anion Receptor

Journal of Inclusion Phenomena and Macrocyclic Chemistry, 2006
Crownophanes composed of 28-membered ring atoms having two hydroxy groups, two amide groups, and aromatic parts such as naphthalene rings and either pyridine or benzene ring, can bind anions with high affinity and selectivity. The anion-coordination ability of these species has been observed by 1H NMR techniques.

Bambusuril Anion Receptors

Israel Journal of Chemistry, 2017
Abstract Bambusurils are macrocyclic compounds whose synthesis was first reported in 2010. Since then bambusurils have been investigated mainly because of its six‐membered homologues’ outstanding binding affinities towards inorganic anions in both organic solvents and water.

Anion-driven structures of radially arranged anion receptor oligomers

Chemical Communications, 2013
Radially arranged oligomers of π-conjugated acyclic anion receptors showed various anion-driven structures depending on the positions and numbers of the receptor units.

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.

Macrocyclic receptor for pertechnetate and perrhenate anions

Organic & Biomolecular Chemistry, 2011
The design and synthesis of a neutral macrocyclic host that is capable of perrhenate and pertechnetate recognition is described. The anion affinities and underlying coordination modes were estimated by several experimental and theoretical methods including a new technique--reverse (99)Tc NMR titration.
