“…The second series of ligands were synthesized using the following general procedure [44]. Under nitrogen, solutions of N-(1-bromoethyl)-1,8-naphthalimide (7) (0.305 g, 1.0 mmol) and 2,2'-dipyridylamine (0.20 g, 1.1 mmol) were suspended in acetonitrile.…”

“…As shown in Figure 1, the absorption and emission spectra of solution 1 were in the visible region ( ex = 426 nm, em = 512 nm) and there was a large Stokes shift approximately 86 nm in solution of 1. It should be noted that the modification of 2-(3-(2-aminoethylsulfanyl)propylsulfanyl)ethanamine at the 4position of the naphthalimide fluorophore can induce the absorption and the emission spectra to the red region compared to the reported sensors [8,35], modifying naphthalimide fluorophore at -position which exhibited absorption and fluorescent emissions in the UV region ( ex , em < 400 nm).…”

With an aim to develop the new sensors for optical detection of Hg2+ions, two novel fluorometric sensors were designed and successfully prepared using 2-(3-(2-aminoethylsulfanyl)propylsulfanyl)ethanamine and one or twoN-methylnaphthalimide moieties (1and2). Sensor1was obtained viaN-alkylation,N-imidation and a one-pot nucleophilic aromatic substitution, andN-formylation of the amine, while sensor2was prepared viaN-alkylation,N-imidation, and nucleophilic aromatic substitution. The characterization, including1H NMR,13C NMR, and mass spectrometry, was then performed for1and2. The Hg2+-binding behaviors of the sensors were investigated in terms of sensitivity and selectivity by fluorescence spectroscopy. Sensor1especially provided the reversible and highly Hg2+-selective ON-OFF fluorescence behavior by discriminating various interfering ions such as Pb2+, Co2+, Cd2+, Mn2+, Fe2+, K+, Na+, and in particular Cu2+and Ag+with a detection limit of 22 ppb toward Hg2+ions.

There is fast growing research on designing and improving the metal recognition methodologies in the ecosystems and biological media. The fluorescent based techniques proved a mile stones for non-invasive metal sensation and quantification in the multichannel environment. Metals as the natural components of Earth's crust are generally present in trace concentrations in the environmental samples where the humic substances have complexation affinity toward them. Iron, zinc and copper are the 1 st , 2 nd and 3 rd adequate elements indispensable to the body in trace playing the crucial roles in many biological processes. However, the unregulated amounts either as excess or deficient may exacerbate deterioration to the vital organs and triggered the progression of complications. Beside these three essential elements, mercury is widely considered to be one of the most hazardous pollutants and highly dangerous elements due to its recognized accumulative and toxic characters in the environment and the ecosystem. In the current scenario, we have tried to summarize the maximum amount of recently developed fluorescent signaling materials for the Cu 2+ , Fe 2+ / Fe 3+ , Zn 2+ and Hg 2+ . The spectral shifting in the molecules on metal chelation, mode of complexation and stoichiometries of resulting adducts have been discussed in detail. Furthermore, the molecules which have been reported as intracellular metal detector via bioimaging are specifically highlighted that might be useful for the design and development of cell viable and membrane permeable molecular probes in the future perspective.
