Abstract

Two new emissive chemosensors based on coumarin-343 have been synthesized, and their photophysical studies conducted. L1 contains an aza-thio macrocycle ring as the chelating unit, which has great affinity for soft metal ions, whereas L2 is a parent species without macrocyclic unit. Both compounds were separated by column chromatography and characterized by elemental analysis, ¹H,¹³C NMR, UV-vis and FAB mass spectroscopy. The X-ray structures of L1 and L2 and the supramolecular interactions in the solid state are discussed. Preliminary results on the metal-ion sensing effects of the ligands are presented. Titrations with Ag⁺, Pd²⁺ and Ni²⁺ have been studied by UV-vis absorption and fluorescence spectroscopy.
