Abstract

Firstly, in this study, aldehyde derivative compound containing 5-chloro-8-hydroxyquinoline was obtained as literature information. Then, for the target compound, which is Schiff base derivative, was obtained from the condensation reaction of the aldehyde derivative compound containing chinolin with salicylaldehyde hydrazone. Chemical structure of synthesized Schiff base compound was confirmed as using various spectroscopic techniques (1H-NMR and 13C-NMR). Then, the interactions of the synthesized Schiff base compound with metals (Li+, Ni2+ Co2+, Ag+, Al3+, Mg2+, Ca2+, Ba2+, Cu2+, Hg2+, Fe2+, Pb2+, Fe3+, Cr3+ and Zn2+) under convenient conditions were investigated using fluorescence spectrophotometry. In the fluorimetric investigations, primarily, the selectivity study was carried out. The free sensor target compound at 538 nm did not produce any significant emission intensity with excitation at 405 nm. The each of the cations (10.0 equiv) were separately added to target compound, only Zn2+ caused to a single band at 538 nm with a notable emission enhancement. As a result of the measurements, it was determined that the target compound had fluorimetric selectivity against only Zn2+ metal within all metals (Li+, Ni2+, Co2+, Ag+, Al3+, Mg2+, Ca2+, Ba2+, Cu2+, Hg2+, Fe2+, Pb2+, Fe3+, Cr3+).
