Abstract

Abstract: The binding behaviour of (thio)urea‐ and amide‐functionalized quinoline‐based anion receptors towards halide anions was investigated in detail in CDCl3 and [D6 ]DMSO solutions by using 1 H and 19 F NMR spectroscopic methods. The electronic, solvent, and fluoro‐substitution effects were studied. The (thio)urea‐ and amide‐functionalized quinoline‐based anion receptors showed medium to strong anion affinity and good selectivity in solution. Single crystals of key compounds were obtained and studied by X‐ray diffraction spectroscopy.
