Özet
A long wavelength fluorescent, squaraine-based chemosensor has been synthesized in one step from commercially available precursors. The resulting squaraine derivative absorbs maximally at 635 nm (epsilon = 260,000) and the emission peak is at 665 nm. This azacrown-appended squaraine signals alkaline and earth-alkaline metal ions in millimolar concentrations in acetonitrile. (C) 1997 Elsevier Science Ltd.
