  • Abstract
    A squarylium dye carrying a monoazacrown moiety has been synthesized and characterized. The new azacrown-squarylium (ACSQ) dye 7 demonstrates sensitivity to Li+ complexation with spectroscopic changes in fluorescence. Complex formation of ACSQ with Cu2+ was also investigated by UV¯Vis spectrometry.
