“…Nonetheless, reports about uorescent sensors for Mg 2+ are still few compared with those on other important ions, such as Zn 2+ , Al 3+ , Hg 2+ and CN À . [14][15][16][17][18][19][20][21][22][23][24][25][26][27] Even so, some methodologies for detecting Mg 2+ are oen interfered with by Zn 2+ and Ca 2+ . To date, as far as we know, b-diketone, crown ether derivatives, and nanoparticles have been employed for selective detection of Mg 2+ ions.…”

“…At the same time, copper is the third most abundant trace element in the human body as well as in many living organisms. Moreover in the literature, only few coumarin based Schiff base were reported and known to selectively recognize for dual sensing of metal ions 23, 29,30 . However, any alternation in the uptake of copper may lead to neurodegenerative disorders such as Menkes and Wilson diseases [11][12][13] , familial amyotropic lateral sclerosis 14,15 and Prion diseases 16 .…”

A new coumarin based Schiff-base chemosensor-(E)-7-(((8-Hydroxyquinoline-2-yl) methylene) amino)-4-(trifluoromethyl)-2H-chromen-2-one (H 12 L) was designed and synthesized. This chemosensor was evaluated as a colorimetric sensor for Fe 3+ and fluorescence "turn on-off" response of Zn 2+ and Cu 2+ using steady-state absorption and fluorescence spectroscopy. In presence of Fe 3+ and Zn 2+ , the absorption intensity as well as the fluorescence emission intensity increases drastically compared to other survey metal ions, with a distinct color change which provide naked eye detection. However, in presence of Cu 2+ , it also exhibits quenching of fluorescence emission intensity which may be due to paramagnetic nature of Cu 2+ ion. The stoichiometric ratio and binding constant were calculated using Benesi-Hildebrand relation and Job's plot analyses giving 1:1 stoichiometry. The interaction and binding nature of H 12 L with Zn 2+ ion was further confirmed by 1 H NMR titration assay and ESI-Mass spectral analysis. The reversibility nature of H 12 L was also studied using EDTA as a chelating ligand. Moreover, H 12 L exhibits two INHIBIT logic gates with two different chemical inputs (i) Zn 2+ (IN1) and Cu 2+ (IN2) and (ii) Zn 2+ (IN1) and EDTA (IN2) and the emission as output. Again, an IMPLICATION logic gate is obtained with Cu 2+ and EDTA as chemical inputs and emission as output mode. Both H 12 L and metal-complexes were optimized using density functional theory and vibrational frequency calculations confirm that both are at local minima on the potential energy surfaces. The corresponding energy difference between HOMO and LUMO of H 12 L, Zn-complex and Cu-complex are found to be 2.11, 0.81 and 0.17 eV, respectively.A new coumarin based Schiff-base chemosensor has been synthesized and characterized Evaluated as a colorimetric sensor for Fe 3+ and fluorescence turn on-off response of Zn 2+ and Cu 2+ Both Benesi-Hildebrand relation and Job's plot analyses gives 1:1 stoichiometry Free ligand can be reusable and recyclable by treating the complex probe with EDTA Binary logic function of two INHIBIT with an IMPLICATION logic gate is anticipated

“…However, both its deficiency and excess accumulation are associated to the various disorders such as anemia, damage to the liver and kidney and Alzheimer's and Parkinson's diseases [7][8][9][10]. Indeed, there are very promising Fe 3+ -fluorescent sensor which were prepared in a simple procedure and were able to detect this ion in trace amount [11][12][13][14]. Since Fe 3+ is mostly occurred in aqueous media, it is of great importance that the sensor be able of on-line detection of this ion directly in water.…”

A novel organic-inorganic hybrid optical sensor (SBA-NCO) was designed and synthesized through immobilization of isocyanatopropyl-triethoxysilane and 1-amino-naphthalene onto the surface of SBA-15 by post-grafting method. The characterization of materials using XRD, TEM, N2 adsorption-desorption, and FT-IR techniques confirmed the successful attachment of organic moieties and preserving original structure of SBA-15 after modification step. Fluorescence experiments demonstrated that SBA-NCO was a highly selective optical sensor for the detection of Fe(3+) directly in water over a wide range of metal cations including Na(+), Mg(2+), Al(3+), K(+), Ca(2+), Cr(3+), Mn(2+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+), and Pb(2+) in a wide pH values.
