Selective fluorescence sensing of ferric ion with novel triazolethione Schiff bases probes

[摘要] New triazolethione Schiff base derivatives 3a–f were synthesized. The structures of the products were characterized by elemental analysis, 1 H NMR, 13 C NMR, IR and MS. Their complexation properties to different heavy and transition metal ions were studied by UV-Vis and fluorescence spectroscopy. Compound 3a shows selective recognition of Fe 3+ with a 1:1 stoichiometric complex formation.
