ABSTRACT

Five new Schiff base ligands were synthesized from the reaction of p-aminoazobenzene with benzaldehyde, 3-nitrobenzaldehyde, 4-chlorobenzaldehyde, 4-hydroxybenzaldehyde, and cinnamaldehyde. These Schiff base compounds have been characterized by elemental analyses, FT-IR, 1H NMR, and 13C NMR spectroscopic measurements. Computational studies further revealed their molecular geometry and electronic properties at the PM6 level by performing the semi-empirical molecular orbital theory.
