A New pH-Dependent Macrocyclic Rhodamine B-Based Fluorescent Probe for Copper Detection in White Wine
For efficiently measuring copper (II) ions in the acidic media of white wine, a new chemosensor based on rhodamine B coupled to a tetraazamacrocyclic ring (13aneN<sub>4</sub>CH<sub>2</sub>NH<sub>2</sub>) was designed and synthesized by a one-pot reaction using eth...

| description | For efficiently measuring copper (II) ions in the acidic media of white wine, a new chemosensor based on rhodamine B coupled to a tetraazamacrocyclic ring (13aneN<sub>4</sub>CH<sub>2</sub>NH<sub>2</sub>) was designed and synthesized by a one-pot reaction using ethanol as a green solvent. The obtained chemosensor was characterized via NMR, UV and fluorescent spectra. It was marked with no color emission under neutral pH conditions, with a pink color emission under acidic conditions, and a magenta color emission under acidic conditions where copper (II) ions were present. The sensitivity towards copper (II) ions was tested and verified over Ca<sup>2+</sup>, Ag<sup>+</sup>, Zn<sup>2+</sup>, Mg<sup>2+</sup>, Co<sup>2+</sup>, Ni<sup>2+</sup>, Fe<sup>2+</sup>, Pb<sup>2+</sup>, Cd<sup>2+</sup>, Fe<sup>3+</sup>, and Mn<sup>2+</sup>, with a detection limit of 4.38 <inline-formula> <math display="inline"> <semantics> <mrow> <mo>×</mo> </mrow> </semantics> </math> </inline-formula> 10<sup>−8</sup> M in the fluorescence spectrum. |
