Fluorinated tungsten calixarene imido complexes were synthesized and used as receptors to detect and differentiate neutral organic compounds. It was found that the binding of specific neutral organic molecules to the tungsten centers induces an upfield shift of the fluorine atom appended on the arylimido group, the extent of which is highly dependent on electronic and steric properties. We demonstrate that the specific bonding and size-selectivity of calixarene tungsten–imido complex combined with [superscript 19]F NMR spectroscopy is a powerful new method for the analysis of complex mixtures.
