chemosensor tailored for Cr (VI) ion detection in semi-aqueous solutions. demonstrates notable alterations in coloration and reduced fluorescence output upon interaction with Cr (VI) ions, showing remarkable selectivity even amidst other interfering metal ions. Fluorescence spectral titrations were employed to ascertain the binding constant and detection thresholds of the complex, with LOD and LOQ established
