Abstract:

1-(2-hydroxyphenyl) ethanone synthesized by the condensation of 2-hydroxyacetophenone and ethanolamine has been known as potential ligating molecules for coordinating copper. Herein, it is explored as a receptor to study its optical behavior towards some metallic species via naked eye chemo-sensing, UV-Visible spectrometry and Fluorescence studies using water -methanol (80:20) mixed solvent system. Interestingly, the receptor behaved as a colorimetric switch selectively for Fe (III) species and fluorphore for Zn (II) and Cd (II) species. The optical behavior of receptor molecule (5�?10-4 M) towards Fe3+ was in the range 0.05-0.85 mM in water-methanol mixture, which showed a color switch from yellow to red with the appearance of corresponding absorbance bands centered at 329 and 387 nm. Furthermore, receptor molecule �??turned on�?� the fluorescence at excitation of 380 nm with respective emission bands at 451 nm and 448 nm for Zn and Cd. Moreover, the strategies were optimized to determine these metal ions in pharmaceutical samples and environmental natural samples.
