Calix[4]arene Based Dual Fluorescent Sensor for Al(3+) and S2O7 (2.).
Specific functionalized calix[4]arene based fluorescent chemosensor was synthesized for cations and anions binding efficiency examination. Receptor C4MA displayed strong affinity for Al(3+)and S2O7 (2-) with enhanced fluorescence intensity. The selective response of C4MA was investigated in the presence of different co-existing competing ions. The limit of detection (LOD) of Al(3+)and S2O7 (2-) was calculated as 2.8 × 10(-6) M and 2.6 × 10(-7) M respectively. Sensor C4MA forms (1:1) stoichiometric complex with both Al(3+) and S2O7 (2-) and their binding constants were calculated as 12.1 × 10(4) and 8.3 × 10(3) respectively. Complexes were also characterized through FT-IR spectroscopy. Graphical Abstract ᅟ.
