Naphthalene-based Azo-azomethine Chemosensor: Naked Eye Detection of Fluoride in Semi-aqueous Media
A new azo-azomethine chemosensor containing active phenolic sites, H2L, has been designed and synthesized for rapid detection of inorganic fluoride over the other anions, such as Clˉ, Brˉ, Iˉ, AcOˉ, H2PO4ˉ, NO3ˉ, N3ˉ in DMSO/water (90/10) media. The 1H NMR titration revealed that the colorimetric response was considered to be the direct consequence of hydrogen-bond formation between phenolic gr...
متن کاملA colorimetric probe for the selective naked-eye detection of Pb(II) ions in aqueous media.
A new colorimetric molecular probe based on a 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dye selectively binds Pb(II) ions in aqueous solutions, allowing for highly sensitive naked-eye detection.
متن کاملNaked-eye and Selective Detection of Mercury (II) Ions in Mixed Aqueous Media Using a Cellulose-based Support
A test paper for high-selectivity detecting Hg2+ ions in mixed acetonitrile-watersolutions has been achieved using a bis(ferrocenyl) azine, as chromogenic chemosensormolecule, and a solid cellulose fibre, as a substrate. Depending on the amount of mercuryions in contact with the detecting molecule a spectacular color change in the celluloseindicator is produced, being possible to determine the ...
متن کاملHydrophobic poly(azomethine-urethane) Film for Detection of Fe3+ Ions in Aqueous Media
A new and easy-to-make polymer film sensor was prepared by dip-coating technique and this film used as fluorescent chemosensor for the detection of metal ions in aqueous solution. The proposed film sensor exhibited dual emissions at 540 and 582 nm under a single excitation wavelength. The fluorescence behavior of this film sensor toward metal ions has been investigated using these two wavelengt...
متن کاملSynthesis and characterization of azo-guanidine based alcoholic media naked eye DNA sensor
DNA sensing always has an open meadow of curiosity for biotechnologists and other researchers. Recently, in this field, we have introduced an emerging class of molecules containing azo and guanidine functionalities. In this study, we have synthesized three new compounds (UA1, UA6 and UA7) for potential application in DNA sensing in alcoholic medium. The synthesized materials were characterized ...
