There’s a star on the rise in the world of supramolecular chemistry. Cyanostar, a new star-shaped macrocycle (shown), can pull weakly coordinating anions, which previously defied capture, out of solution (Nat. Chem. 2013, DOI: 10.1038/nchem.1668). The compound’s anion-sequestering abilities could find applications in environmental remediation of perchlorate and molecular sensing of biological phosphates. Although cyanostar is a neutral molecule, it . . .
