Indole-Based Macrocycles as a Class of Receptors for Anions

Indole-Based Macrocycles as a Class of Receptors for Anions

Shift work: The identity of an anion complexed to indole‐based macrocycles can be determined by the NMR chemical shift of the NH protons (see picture). The difference in the chemical shifts arises from a difference in the strength of the hydrogen‐bonding interactions between the macrocycles and the...

Zusammenfassung:Shift work: The identity of an anion complexed to indole‐based macrocycles can be determined by the NMR chemical shift of the NH protons (see picture). The difference in the chemical shifts arises from a difference in the strength of the hydrogen‐bonding interactions between the macrocycles and the anions.
