Encapsulation and selectivity of sulfate with a furan-based hexaazamacrocyclic receptor in water

Org Biomol Chem. 2014 Apr 7;12(13):2045-8. doi: 10.1039/c4ob00116h. Epub 2014 Feb 20.

Abstract

A furan-based hexaazamacrocycle encapsulates a sulfate anion in its cavity showing strong affinity and selectivity for sulfate in water over a wide range of inorganic anions. The DFT calculations demonstrate that the receptor provides binding sites as hydrogen bonding donors and electrostatic positive charges for the strong binding of sulfate.
