Neutral iodotriazole foldamers as tetradentate halogen bonding anion receptors.
Neutral tetradentate halogen bond donor foldamers were synthesised and exhibit enhanced anion affinities over their hydrogen bonding analogues, displaying iodide selectivity over lighter halide, carboxylate and dihydrogen phosphate anions. A foldamer with a chiral (S)-binaphthol motif was demonstrated to distinguish between enantiomers of chiral anions.
متن کاملEvidence for Halogen Bond Covalency in Acyclic and Interlocked Halogen-Bonding Receptor Anion Recognition
The synthesis and anion binding properties of novel halogen-bonding (XB) bis-iodotriazole-pyridinium-containing acyclic and [2]catenane anion host systems are described. The XB acyclic receptor displays selectivity for acetate over halides with enhanced anion recognition properties compared to the analogous hydrogen-bonding (HB) acyclic receptor. A reversal in halide selectivity is observed in ...
متن کاملCoordination chemistry of anions through halogen-bonding interactions.
While an IUPAC definition for hydrogen bonding was only released in 2011 after decades of discussions in the scientific community (Arunann et al., 2011), it did not take such a long time to come up with an analogous definition of halogen bonding (Desiraju et al., 2013), following a revival of this interaction in the literature, which can be traced back to the early 1990s. The identification of ...
متن کاملHalogen- and hydrogen-bonding triazole-functionalised porphyrin-based receptors for anion recognition.
Iodotriazole and triazole anion recognition groups have been integrated into a picket-fence zinc(ii)-metalloporphyrin scaffold to produce receptors for anion recognition and sensing applications. (1)H NMR and UV/visible spectroscopic investigations reveal both host systems exhibit strong anion binding affinities in a range of solvent media. Importantly, the halogen-bonding iodotriazole-containi...
