Anions, due to their ubiquity and technological and biological relevance, constitute important targets for the construction of molecular receptors capable of their capture, sensing, and transport. To ensure efficient binding, anion receptors are typically equipped with strong hydrogen bond donors (NH, OH), halogen bond donors (e.g. polarized I atoms), or positively charged groups, which are known to strongly interact with anions. CH-based anion receptors are inherently weaker, but offer unique selectivity, high stability, and lipophilicity, which make them appealing for certain applications. In particular, their lipophilic nature and high resistance to deprotonation make them promising candidates for transmembrane anion carriers.
