Naked eye detection of anions by alkynyl-ruthenium exo-receptors: selective recognition of fluoride anion.
Alkynyl-ruthenium complexes bearing terminal hydrogen-bonding receptors act as efficient anion sensors exhibiting large guest-induced colour changes and show unexpectedly high selectivity to fluoride ions.
