“…Nevertheless, the preparation of selective chemosensors, especially for detection, quantification, and/or removal of anions from polluted waters, is still challenging [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. The recognition of a specific anion by a receptor can induce a response, being it an electrochemical or optical transition (e.g., color change or fluorescence ON/OFF), that can be used to monitor the presence and, in some cases, the concentration of an anionic guest [ 11 , 12 ]. This performance is predominantly useful for the detection of environmentally harmful anions (e.g., nitrate and phosphate) [ 13 , 14 ], detection of potentially toxic anions (e.g., cyanide) [ 15 ], or in medical diagnostics [ 16 ].…”

Anionic species are one of the most common pollutants in residual and freshwaters. The presence of anthropogenic anions in water drastically increases the toxicity to living beings. Here, we report the preparation of a new optical active material based on tri(tosylamino)phthalocyanines grafted to ferromagnetic silica nanoparticles for anion detection and removal. The new unsymmetrical phthalocyanines (Pcs) proved to be excellent chemosensors for several anions (AcO−, Br−, Cl−, CN−, F−, H2PO4−, HSO4−, NO2−, NO3−, and OH−) in dimethyl sulfoxide (DMSO). Furthermore, the Pcs were grafted onto magnetic nanoparticles. The resulting novel hybrid material showed selectivity and sensitivity towards CN−, F−, and OH− anions in DMSO with limit of detection (LoD) of ≈4.0 µM. In water, the new hybrid chemosensor demonstrated selectivity and sensitivity for CN− and OH− anions with LoD of ≈0.2 µM. The new hybrids are easily recovered using a magnet, allowing recyclability and reusability, after acidic treatment, without losing the sensing proprieties.

“…As well, coumarins exhibit beneficial effects via diminishing the risk of cancer and other brain and cardiovascular ailments. [19] In addition, coumarins are also available for various applications, including laser dyes, fluorescent probes, [20,21] nonlinear optical chromophores, photosensitizers, [22,23] chemical sensors, [24][25][26][27][28] optical brighteners, [29] and also textile applications of fluorescent azo dyes. [30,31] Because coumarins are wellrecognized as chromophores, they have high fluorescent and high quantum yield.…”

N methylene]-2-cyanoacetohydrazide (3) was synthesized in excellent yield from the condensation of 4-Chloro-2-oxo-2H-chromene-3-carbaldehyde with cyanoacetohydrazide. Compound 3 was utilized as a building block to synthesize novel coumarin and heterocyclefused coumarin derivatives. The chemical structures of all the new coumarin compounds were identified by spectral analyses. Some of the new coumarins compounds were screened in human cancer cell lines (HEPG-2, MCF-7, HCT-116 and PC-3) to learn about their cytotoxic effects in addition to the study of their DNA damage and antioxidant activity. Three of these compounds exhibited remarkable antioxidant and anti-proliferative activities. Moreover, they have the capability to protect DNA from damage induced by bleomycin. Molecular docking, DFT and molecular electrostatic potential studies were performed on the compounds in vitro.[a] M. A.
