Tetrel Bonding in Anion Recognition: A First Principles Investigation. [PDF]
Molecules, 2022 Twenty-five molecule–anion complex systems [I4Tt···X−] (Tt = C, Si, Ge, Sn and Pb; X = F, Cl, Br, I and At) were examined using density functional theory (ωB97X-D) and ab initio (MP2 and CCSD) methods to demonstrate the ability of the tetrel atoms in ...

The fluoride permeation pathway and anion recognition in Fluc family fluoride channels. [PDF]
Elife, 2021 Fluc family fluoride channels protect microbes against ambient environmental fluoride by undermining the cytoplasmic accumulation of this toxic halide. These proteins are structurally idiosyncratic, and thus the permeation pathway and mechanism have no ...

Chiral anion recognition using calix[4]arene-based ureido receptors in a 1,3-alternate conformation. [PDF]
Beilstein J Org Chem, 2020 The introduction of chiral alkyl substituents into the lower rim of calix[4]arene immobilised in the 1,3-alternate conformation led to a system possessing a preorganised ureido cavity hemmed with chiral alkyl units in the near proximity.

Creating molecular macrocycles for anion recognition. [PDF]
Beilstein J Org Chem, 2016 The creation and functionality of new classes of macrocycles that are shape persistent and can bind anions is described. The genesis of triazolophane macrocycles emerges out of activity surrounding 1,2,3-triazoles made using click chemistry; and the same

Pyrrole-pyridine and pyrrole-naphthyridine hosts for anion recognition. [PDF]
Molecules, 2015 The association constants of the complexes formed by two hosts containing pyrrole, amide and azine (pyridine and 1,8-naphthyridine) groups and six guests, all monoanions (Cl−, CH3CO2−, NO3−, H2PO4−, BF4−, PF6−), have been determined using NMR titrations.

Fluoride Anion Recognition by a Multifunctional Urea Derivative: An Experimental and Theoretical Study. [PDF]
Sensors (Basel), 2016 In this work we demonstrate the ability of a multifaceted N,N′-disubstituted urea to selectively recognize fluoride anion (F−) among other halides. This additional function is now added to its already reported organocatalytic and organogelator properties.
