Azo ligands containing salicyaldimine-based ligand as side chains can be used in the
production of chemical sensors because they show a significant change of color of the
solution and maxima of the absorption band when they interact with transition metal ions or
anions [1-3]. Therefore among the wide range of materials that may be suitable for the
electronic and optical applications, salicyaldimine-based ligands are of particular interest.
In this work, two new azo Schiff-bases I and II were prepared from 1-(3-formyl-4-
hydroxophenylazobenzene) and 4-nitro-1,2-phenylenediamine or 4-chloro-1,2-
diaminobenzene in methanol solution. Two compounds were characterized with FT-IR,
1
H
NMR and elemental analysis techniques. Also, optical properties of these compounds were
investigated by UV-vis spectroscopy in the presence of some metal ion transitions.
