A naked-eye colored chemodosimeteric probes 4a-f, based on Schiff-azo dye conjugates were synthesized and characterized. All compounds 4a-f exhibited excellent selectivity and high sensitivity in absorbance toward detection of Fe3+ in alcoholic solutions under neutral pH conditions. The detection limit of the probe was shown to be up to 0.05 ppm. A simple paper test strip system for the rapid monitoring of Fe3+ was developed, indicating their convenient use in environmental samples. Electrochemical analysis of metal free conjugates and iron chelated probes confirmed the chelation of ligands. Graphical Abstract.
