The synthesized fluorescent probe exhibited a strong emission band at 470\u2009nm upon excitation at 410\u2009nm with a quantum yield of 0.95\u2009\u00b1\u20090.05. Incremental additions of Zn (II) from 2.5 to 37.5\u2009\u03bcM induced a pronounced turn\u2010off response in fluorescence intensity. An excellent linearity (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.9999) was established between the quenching magnitude and Zn (II) concentration, with a limit of detection (LOD) reaching 0.47\u2009\u03bcM, indicative of exceptional sensitivity. This fluorescence attenuation was ascribed to a chelation\u2010induced static quenching mechanism, as corroborated by Stern\u2013Volmer analysis, confirming the formation of a non\u2010emissive Zn (II)\u2013probe complex. The protocol demonstrated practical utility in assaying Zn (II) within commercial tablets and river water matrices, yielding recovery rates of 97.70%\u2013102.85%. These results demonstrate the high selectivity of the fabricated probe and its negligible susceptibility to matrix interferences. Collectively, this methodology offers a facile, economical one\u2010pot synthesis route alongside a highly sensitive spectrofluorimetric platform, thereby extending its scope for real\u2010world environmental and pharmaceutical monitoring.\n
