A selective colorimetric and fluorescent chemosensor based-on naphthol for detection of Al3+ and Cu2+

“Turn-on” fluorescent and colorimetric determination of Cu2+ ions in aqueous media based on a Rhodamine-N-phenyl Semicarbazide derivative

“…For this reason, considerable attention has been focused on the design of fluorescent chemosensors for Cu 2+ ion due to the highly sensitive, quick, and nondestructive advantages of the fluorescence method in the past decade [21][22][23][24]. In terms of sensitivity concerns, chemosensors exhibiting fluorescence enhancement (fluorescence "turn-on") upon Cu 2+ ion complexation are favored over those showing fluorescence quenching (fluorescence "turn-off") under Cu 2+ binding.…”

A colorimetric chemosensor for the sequential detection of copper(II) and cysteine

“…The World Health Organization (WHO) has recommended the maximum limit of copper in drinking water to be at 2 ppm (30 µM) [10,11]. For these reasons, much effort has been devoted to the design of various chemosensors specific for Cu 2+ detection [12][13][14][15][16][17][18].…”

Fluorescent Character of Cu(I/II) Complexes with Bisquinoline-based Ligands and Fluorometric Detection of Reductants

“…Although the detection of metal ions with fluorescent ligands in water or organic solvents has been reported, [8][9][10][11] the detection of water-soluble reductants with fluorescence caused by the change of oxidation number of metal ions has not been reported.…”

“…The fluorescence of the ligands is not necessarily quenched in a Cu(I) complex because the d 10 electron configuration has no magnetic moment, and many fluorescent Cu(I) complexes have been reported. [1][2][3][4] However, almost all of the reported fluorescent Cu(I) complexes have been in the solid state or in organic solvents.…”
