Halogen-bonding for visual chloride ion sensing: a case study using supramolecular poly(aryl ether) dendritic organogel systems†
Abstract
A convenient and straightforward method for the visual recognition of chloride ion has been established through a chloride-responsive dendritic organogel. The specificity was largely attributed to the higher binding affinity of the dendritic gelator for chloride compared with other anions through halogen bonding interactions.
