A Ratiometric Selective Fluorescent Probe Derived from Pyrene for Cu2+ Detection
نویسندگان
چکیده
A novel ratiometric Cu2+-selective probe was rationally constructed based on pyrene derivative. Compared to other tested metal ions, the presented selective recognition for Cu2+ which could be detected by a significant turn-on fluorescent response at 393 nm and 415 nm. Under optimized conditions, detection limit of 0.16 ?M in aqueous media found. Besides this, 1:1 metal–ligand complex confirmed MS spectra Job’s plot experiment, binding mode also studied 1H NMR experiment. Meanwhile, fluorescence imaging living cells performed detect with satisfactory results.

A highly selective ratiometric fluorescent probe, which contains an aminonaphthalimide fluorophore and a self-immolative spacer for 1,4-dithiothreitol (DTT) detection was designed and synthesized. The probe displays a 66 nm red-shift of fluorescence emission and the color changes from colorless to jade-green upon reaction with DTT. These properties are mechanistically ascribed to the strong red...
