Abstract
Three structurally similar compounds, 1-3, bearing a fluorescence chromophore to which are appended morpholine, thiomorpholine and methylpiperazine substituents, display opposite fluorescence responses to pH changes, in contrast to that observed for fluorescein; 1 and 2 have extremely high binding selectivity towards Ag+ ions and show completely different fluorescent and colorimetric changes upon addition of Ag+, and the differences are proposed to be associated with different binding modes of 1 and 2 to this metal ion. © The Royal Society of Chemistry.
