  • Title: Selective anion sensing by chiral macrocyclic receptors with multiple hydrogen-bonding sites.
    Author: Ema T, Okuda K, Watanabe S, Yamasaki T, Minami T, Esipenko NA, Anzenbacher P.
    Journal: Org Lett; 2014 Mar 07; 16(5):1302-5. PubMed ID: 24528472.
    Abstract:
    Chiral macrocycles featuring sulfonamide and/or amide groups as anion-binding sites were synthesized. X-ray crystal structures and DFT calculations have shown that they adopt different conformations that may lead to unique binding behavior. Indeed, various anions could be sensed by their colorimetric and/or fluorescence signal output. The chiral macrocycles showed chiral recognition for chiral anions. Furthermore, a multisensor array with two or four chiral receptors discriminated seven phosphate anions (AMP, ADP, ATP, CMP, GMP, Pi, and PPi) with 100% classification accuracy.
