Systematic Study of Podand Molecules for Synergistic Halogen and Hydrogen Bond‐Driven Anion Recognition in the Solid State

Abstract

AbstractThe increasing demand of species for the efficient capture and sensing of anions benefits from a systematic study of anion binding capabilities in the solid state. This work reports a detailed crystallographic study of ten structurally related podands and shows that these charged receptors bind anions with a combination of charge‐assisted halogen and hydrogen bonds. Computational tools helped in highlighting the role of the different involved interaction and afforded possible design principles for the design of improved podands.
