چکیده
The synthesis of a series halogen bonding (XB) acyclic anion receptors based on novel 1,2-iodo-triazolium-triazole benzene motif is reported. A combination one- and two-dimensional 1H 19F NMR spectroscopic techniques elucidate key conformational effects associated with the incorporation ortho-substituted iodo-triazole XB donors. titration experiments highlight recognition potency mono-cationic iodo-triazolium-triazole receptor, remarkably forming stronger halide complexes in comparison to dicationic hydrogen (HB) bis-proto-triazolium receptor analogue. X-ray crystal structure analysis provide insights into binding induced changes coordination modes, revealing unique electronic steric consequences multidentate donor arrays.

Halogen- 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...

Triazole and triazolium groups have been integrated into a zinc(II) metalloporphyrin-based structural framework to produce two porphyrin-cages for anion sensing applications. UV/visible spectroscopic titration investigations reveal both host systems exhibit strong anion binding affinities, with the positively-charged triazolium-porphyrin cage capable of colorimetric sensing halides, fluoride an...
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 کاملSelective Nitrate Recognition by a Halogen‐Bonding Four‐Station [3]Rotaxane Molecular Shuttle
The synthesis of the first halogen bonding [3]rotaxane host system containing a bis-iodo triazolium-bis-naphthalene diimide four station axle component is reported. Proton NMR anion binding titration experiments revealed the halogen bonding rotaxane is selective for nitrate over the more basic acetate, hydrogen carbonate and dihydrogen phosphate oxoanions and chloride, and exhibits enhanced rec...
متن کاملActive‐Metal Template Synthesis of a Halogen‐Bonding Rotaxane for Anion Recognition
The synthesis of an all-halogen-bonding rotaxane for anion recognition is achieved by using active-metal templation. A flexible bis-iodotriazole-containing macrocycle is exploited for the metal-directed rotaxane synthesis. Endotopic binding of a Cu(I) template facilitates an active-metal CuAAC iodotriazole axle formation reaction that captures the interlocked rotaxane product. Following copper-...
