“…Ligands containing 1,2,3‐triazoles ( IV – VI ) have also been reported as good candidates for sensing cations and anions (Figure 2). [20,21,22,23,24,25] A wide variety of colorimetric probes 26 have been developed for the recognition of the Fe 3+ ion [27,28,29,30,31] . However, there are various shortcomings of these chemosensors such as lack of selectivity, slow response time, interference of competitive metal ions and recyclability, which impede their practical applications.…”

Three novel isatin‐triazole tethered tetrahydropyridine‐based colorimetric chemosensors were synthesized for selective recognition of Fe3+ ions. Their selectivity and sensitivity were investigated through colorimetric and UV‐Visible studies in a mixed‐aqueous medium (MeOH/H2O (7 : 3, v/v)). The binding stoichiometry of Chemosensor 3‐methyl 1‐phenyl (5S,6R)‐5‐bromo‐6‐(4‐((2,3‐dioxoindolin‐1‐yl)methyl)‐1H‐1,2,3‐triazol‐1‐yl)‐5,6‐dihydropyridine‐1,3(2H)‐dicarboxylate (6 a) was found to be 1 : 1 with the highest binding constant Ka, 8.6×103 M−1. The detection limit of 6 a for Fe3+ ions (0.47 μM) was much lower than the maximum permissible limit of Fe3+ ion according to Environmental Protection Agency (EPA). Moreover, the 6 a‐Fe3+ complex was found to be recyclable upon the addition of EDTA. Furthermore, the reversible colorimetric changes of 6 a on adding Fe3+ ions and EDTA were found to mimic the ‘INHIBIT’ molecular logic gate. The chemosensor 6 a recognizes Fe3+ ions by binding through oxygen atoms of isatin as confirmed by Density Functional Theory (DFT) studies.

Two new sulfur-containing ferrocenylimidazo [4,5-b]pyridines, 2-ferrocenyl-5-(thiophen-2-yl)-1H-imidazo [4,5-b]pyridine (L1) and 2-ferrocenyl-5-(thiophen-3-yl)-1H-imidazo[4,5-b]pyridine (L2), were synthesized and characterized. L1 and L2 behaved as highly selective fluorescent "turn-off", redox (ΔE 1/2 = 0.25 V for L1 and ΔE 1/2 = 0.22 V for L2) and UV active receptors for Hg 2 + ions through the formation of the corresponding 2 : 1 and 1 : 1 (receptor:metal ion) complexes, with detection limits 4.47 × 10 À 8 M and 2.21 × 10 À 7 M, respectively. Furthermore, the quenched fluorescence of L1 was recovered on iodide ion addition. The sensing mechanism study suggested that although the imidazo[4,5-b]pyridine is the main coordination unit providing N, N binding sites, the added thienyls have improved the fluorescence emission and Hg 2 + sensing selectivity of L1 and L2, and obviously influenced the coordination mode. Finally, living cell imaging and test strip experiments demonstrated the potential application of L1 in fluorescent visualization of Hg 2 + ions in biological and environmental systems.
