- Abstract
This article reports the selective sensing ability of a newly synthesized calix[4]arene Schiff base (C4TSB) derivative. C4TSB exhibited strong turn-off fluorescence affinity for Hg and Au. The selective sensing ability of receptor was investigated in the presence of different co-existing competing ions. The limit of detection for Hg and Au was determined as 1.9 × 10 and 1.0 × 10 M, respectively. Receptor forms 1:1 stoichiometric complex with both metals and their binding constants were calculated as 7.9 × 10 M for Hg and 5.7 × 10 M for Au. Complexes were also characterized through FT-IR spectroscopy.
