Scientists in the UK have designed a novel meta-xylenediamide macrocycle containing rotaxane anion host.
Following on their pioneering work in the area, the team led by Paul Beer at Oxford University demonstrates a unique guest binding effect in which the interlocked host is able to bind chloride and bromide anions selectively, vs. more basic oxoanions such as dihydrogen phosphate and acetate. Their research highlights how only the monoatomic halides are able to enter the rotaxane cavity, while the larger oxoanions bind to the periphery.
Researchers in a number of ‘supramolecular fields’, such as host-guest chemistry, anion binding, self-assembly, or molecular machines, will be interested in this high-impact chemistry.
