dc.description.abstractAs the presence of (Fe3+) is strongly associated with many environmental and biomedical analysis, effective sensing methods are of great importance for monitoring Fe3+ levels in these systems. In this study, we synthesized a new rhodanine-based azo dye (4d) and compared it with compound (4c) which showed the best sensitivity and selectivity among our previously reported compounds. The interaction behaviors with Fe3+ ions using UV/vis, fluorescence, IR, and NMR spectrometric techniques were investigated. The spectroscopic characterization revealed that azo 4d showed high affinity towards Fe3+ ions with association constant of 5.35 × 108 M?1. Furthermore, it showed high sensitivity towards Fe3+ ions with detection limit of 7.05 µM. These results are almost similar to that of azo 4c. The molar ratio and Benesi–Hildebrand methods confirmed the formation of complexes between azo 4c,d and Fe3+ with 1:2 binding stoichiometry. NMR and IR analyses confirmed the coordination between Fe3+ and the nitrogen atom of the NH (hydrazone) group and the oxygen atom of the carbonyl (C=O) group. Owing to its good affinity and high sensitivity for Fe3+, azo 4d showed excellent potential for developing efficient Fe3+ chemosensors. © 2020en_US
