“…The Ninhydrin thiourea derivative 1 has been recrystallised from hot methanol which melts with decomposition at 195°C-205°C. Powder XRD and spectral studies (ESI-S2) of these compounds are consistent with the expected product [22] (SCHEME 1).…”

Transition metals are common in our environment and balanced concentration of them is obligatory for various biological processes [1]. Interestingly non-degradable metals are a major cause of ecological hazards. Prolonged exposure or excessive assimilation of these through food chain cause acute or chronic toxicity [2]. Utilization of industrial wastewater for irrigation and agriculture cause metal polluted lands and increased concentration of metal in the human body via the food chain [3]. Like few transition metals, copper with stable oxidation states occurs naturally in redox enzymes, which involves cyclic oxidation and reduction processes. Although Cu(II) is essential for various biological processes, significant Cu(II) pose health hazards such as prolonged exposure leads to irritation of nose and eyes, and neurodegenerative diseases [4,5]. Experimental Increased concerns about health issues make it essential to develop economically and environmentally benign technologies to identify toxic cations and anions. Although various sophisticated instruments and methods have been developed [6-12] with

“…19,20 On the other hand, excessive Cu 2+ is harmful to the environment, 21 and colorimetric probes for Cu 2+ determination are widely used because they can monitor Cu 2+ both in solution and on test strips, which can be evaluated by the naked eye. 22,23 It has been noted that Schiff base sensors deserve special attention due to their simplicity, sensitivity, easy operation, and low cost. 15 Although a number of sensors towards two of Cu 2+ , Al 3+ , and Zn 2+ ions have been developed, 5,6,17,[23][24][25][26][27] simultaneous selective detection of all three ions by a molecular chemosensor based on a Schiff base scaffold is rarely reported.…”

“…It suggests that the significant role of these groups in binding with metal ions. Particularly, we have observed decreasing and broadening of imine and hydroxy peaks upon complexation with Hg 2+ , Cu 2+ , Cd 2+, and Pb 2+ ions . Further, we observed similar changes when compared to the free R2 with that of Hg 2+ and Cu 2+ complexes (Figure S16b) .…”

“…Among these, the colorimetric chemosensors are inexpensive, and it will detect the presence of an analyte in a small amount sample in which the target moiety is recognized by naked‐eye. On the other hand, colorimetric sensing methods offer numerous advantages in comparison with the other instrumental methods, viz terms of simple synthesis, sensitivity, field monitoring, fast results and they are non‐destructive …”

A Schiff's base colorimetric chemosensors R1–R3 consist of carbohydrazide, and heterocyclic aldehydes have been designed and synthesized for sensing of heavy metal ions. Synthesized receptors were well characterized by various standard spectroscopic techniques. The receptor R1 exhibited multi‐ion selectivity for Cd2+, Hg2+, Pb2+, Cu2+ ions and showed lowest detection limit of 1.9 ppb, for Cd2+ & Hg2+ ions. The receptors R2 and R3 displayed dual ion selectivity (R2 for Hg2+, Cu2+, and R3 for Cu2+, AsO2– ions) in an aqueous medium at ppb levels. The UV–Vis and colorimetric studies confirmed the selectivity and sensitivity of chemosensors R1–R3 in the presence of other interfering metal ions. Further, using the B–H plot, FT‐IR, and mass analysis data, the binding modes, stoichiometric ratios of receptors R1–R3 with the metal ions were investigated. The estimated association constant values were found to be 104 to 105 M–1/M–2. The experimental results are well concordant with that of calculated theoretical DFT results. The receptors R1–R3 exhibited good sensitivity and selectivity compared to literature reports and successfully demonstrated for test strip applications.
