Remarkable chloride over dihydrogen phosphate anion selectivity exhibited by novel macrocyclic bis[ruthenium(II) bipyridyl] and ruthenium(II) bipyridyl–metallocene receptors
Abstract
Novel macrocyclic bis[ruthenium(II)bipyridyl] and ruthenium(II) bipyridyl–metallocene receptors are prepared and shown by 1H NMR and fluorescence emission spectroscopy to exhibit remarkable selectivity for the chloride anion in preference to dihydrogen phosphate.
