Cooperative Anion-π and C-H-Cl Interactions in Multifunctional Naphthalene-Based Receptors for Chloride Recognition: Cage-size Modulation Through Substitution Patterns.

This article focuses on developing selective receptors for chloride. A series of novel receptors based on a rigid naphthalene spacer bearing tetrafluoropyridines (TFPs) in various substitution patterns has been designed and synthsized. The topology of the receptors was confirmed by X-ray cristallography. Their complexation efficiency was essentially studied in the gas phase through mass spectrometry experiments. Density Functional Theory (DFT) calculations and NMR titration were also performed.
