| dc.description.abstract | In this project work, we have synthesized the ligand 4-N,N-dimethylaminophenyl substituted 2,6-dipyrazinylpyridine L. The synthesized ligand on reacting separately with ZnCl2 and CuCl2 resulted in the formation of desired chemosensors ZnCl2L and CuCl2L respectively. This chemosensor ZnCl2L is used to recognize and sense biologically significant pyrophosphate anion (PPi) in the presence of other anions in aqueous acetonitrile (1:1 v/v) solution (buffered with 10 mM HEPES). The sensing study was visualized through colorimetric method also. Zn-L characteristic absorption band of the ZnCl2L receptor which is unaffected in the presence of other anions got suppressed significantly only upon the addition of PPi ion which confirms high selectivity of the synthesized chemosensor ZnCl2L towards PPi. The CuCl2L receptor is used to recognize and sense hazardous and toxin sulphide anion (S2-) in the presence of other anions in aqueous acetonitrile (2:1 v/v) solution (buffered with 10 mM HEPES). The sensing study was visualized through colorimetric method also. Cu-L characteristic absorption band of the CuCl2L receptor which is unaffected in the presence of other anions, but disappeared and simultaneously the absorption bands of the L re-appeared only upon the addition of one equivalent of S2- anion which confirms high selectivity of the synthesized chemosensor CuCl2L towards S2- anion. | |
