Özet:

 In this work, two Schiff base ligands Z2a and Z2b derived from 5-aminoisophthalic acid were synthesized and their structures were characterized by FTIR, 1H13C NMR and mass spectrometries. The compounds were investigated for their chemosensor properties towards metal ions Na, K, Al3, Cr3, Mn2, Fe3, Co2, Ni2, Cu2, Zn2, Cd2, Hg2 and Pb2 were examined using colorimetric and spectrophotometric methods UV-Vis absorption and florescence spectroscopy. Both compounds showed similar sensing properties towards metal ions and they have shown selective sensory properties for Fe3 and Hg2 ions. Moreover, the compounds were examined for their fluorimetric sensing abilities for nitroaromatic compounds 4-nitrofenol NP, nitrobenzene NB, 2,4-dinitrofenol DNP, 1,3,5-trinitrophenol TNP. Both compounds showed higher sensitivities for DNP and TNP than NP and NB. Compound Z2b showed the highest sensitivity for DNP with Ksv value of 2.4104 M-1. Limit of detections for nitroaromatic compounds were calculated and both compounds showed LOD values in micromolar levels. Compound Z2b has shown the lowest LOD value for DNP with 2.77 M.
