“…Iron is one of the most important elements for the biological system, with its involvement in many physiological processes, such as oxygen delivery [35], enzymatic reactions [36], and electron transfer in the mitochondrial respiratory chain [37]. But the excessive accumulation of iron in the human body would lead to various diseases, including hepatitis [38], Alzheimer's disease [39], and Parkinson's disease [40].…”

This paper reports the preparation of green-emissioned CDs by a one-step hydrothermal route with DL-malic acid and ethylenediamine as raw materials and further explored the impacts of the amount of reactants, the reaction time, and temperature upon the optical properties of prepared CDs, to select the optimal preparation parameters. The optical properties, surface groups, and element components of the prepared CDs have been systematically studied by UV-Vis absorption spectra, fluorescence spectra, FTIR, EDS, and XPS. The prepared CDs have been applied to realize the fingerprint development, fluorescence ink, and, specifically, the detection of Fe2+ through an inner filter effect with its detection range at 2.0×10−7−2.3×10−5 mol/L.

“…Cobalt, an essential component of coenzyme B12 and vitamin B12, plays a pivotal role in the synthesis of proteins and functions of many metabolisms . Even though cobalt is crucial to the human body, unnatural concentrations can lead to toxicological effects such as thyroid enlargement, asthma, and decreased cardiac output . Because of its potential dangerousness, the US Environmental Protection Agency recommended cobalt content of 1.7 μM in the drinking water .…”

A novel carboxamide-based colorimetric chemosensor ATA-Msal ((E)-3-((2-hydroxy-3-methoxybenzylidene)amino) thiophene-2-carboxamide) for detecting Cu 2 + and Co 2 + in aqueous solution was synthesized. Sensor ATA-Msal could probe Cu 2 + and Co 2 + by color change from colorless to pale yellow. According to results of Job plot and ESI-mass, the binding modes of ATA-Msal to Cu 2 + and Co 2 + were determined to be a 1 : 1 ratio. The detection limits (0.14 μM and 0.88 μM) of ATA-Msal for Cu 2 + and Co 2 + were much lower than WHO standard (31.5 μM for Cu 2 + ) and US Environmental Protection Agency (EPA) standard (1.70 μM for Co 2 + ). ATA-Msal can be applicable to real samples and test strips, and F À could be used to distinguish between ATA-Msal -Cu 2 + and ATA-Msal -Co 2 + . The sensing process of Cu 2 + and Co 2 + by ATA-Msal was demonstrated by UV-vis titration, ESI-mass, EPR, 1 H NMR titration, and DFT. Results and DiscussionATA-Msal was gained by the combination of 3-aminothiophene-2-carboxamide and 2-hydroxy-3-methoxybenzaldehyde with 29 % yield in ethanol (Scheme 1). It was characterized by 1 H NMR ( Figure S1), 13 C NMR ( Figure S2) and ESI-mass analysis.

“…Additionally, these compounds are thermally and photochemically stable . Furthermore, the imine moiety having π electrons in CN bond prefers metal ions, causing variations in the ICT, thereby resulting in color changes . Thus, we expected that a molecule containing heterocyclic benzofuran moiety and an imine group having a good binding character toward metal ions might exhibit a good selectivity toward a specific metal ion through the unique spectral and color changes.…”

A novel multifunctional colorimetric sensor HMBC ((E)‐3‐((2‐hydroxy‐3‐methoxybenzylidene)amino)benzofuran‐2‐carboxamide), based on 3‐aminobenzofuran‐2‐carboxamide and 2‐hydroxyl‐3‐methoxylbenzaldehyde, was designed and synthesized. The chemosensor HMBC could sense Co2+, Cu2+, and Zn2+ by color changes from colorless to yellow. Limits of detection (0.38, 0.41, and 1.02 μM) of HMBC for Co2+, Cu2+, and Zn2+ were much lower than the New Jersey Department of Environmental Protection (NJDEP) standard (1.70 μM) for Co2+ and the WHO guidelines (31.5 μM and 76 μM) for Cu2+ and Zn2+. Significantly, HMBC could be applied for the quantification of Co2+, Cu2+, and Zn2+ in real samples. The sensing process of HMBC for Co2+, Cu2+, and Zn2+ was well demonstrated by 1H NMR and UV–Visible titrations, Job plots, theoretical calculations, and ESI‐mass spectroscopy.
