Detection of Zinc Ions Using a Fluorescent Compound Derived from a Cyanoacrylic Acid-based Chemosensor

Year: 2025

Type: article

Abstract: This study was initially conducted through the synthesis and characterization of a cyanoacrylic acid based on thiophene-phenylethyl-cyanoacrylic acid (TPC).The receptor cyanoacrylic acid derivative revealed an "off-on" mode with high selectivity and sensitivity to Zn 2+ ions, whereas the selectivity of the optical sensor for Zn 2+ ions was the consequence of chelation-enhanced fluorescence.The possible interference of other metal ions in solution was examined in the presence of different types of metal ion, whereby the results showed high selectivity and sensitivity with a low detection limit of 7.78 × 10 -8 M. Furthermore, the geometry of the TPC molecular structure and electronic properties were examined using density functional theory and time-dependent density functional theory.A comparison between calculation and experimental data yielded results indicating that the compound has potential applications in chemosensors.
