Reversiblechemosensing of hydrosulfide (HS−) in pure water is demonstrated using halogen bonding (XB) fluorescent hosts. The XB receptors exhibit characteristic selective quenching of fluorescence upon binding HS− whereas the hydrogen bonding receptor analogues proved incapable of functioning as chemosensors under aqueous conditions.
