In the past three decades, the synthesis, structure and properties of Schiff base complexes have stimulated much interest for their noteworthy contributions in single molecule-based magnetism, material science, catalysis of many reactions such as carbonylation, hydroformylation, reduction, oxidation, epoxidation and hydrolysis, etc. Schiff bases have wide applications in many biological fields. The study of Schiff base has been fast developing on account of the wide variety of ligand formations depending on the carbonyl and amine groups. Studies on new classes of chemotherapeutic Schiff bases are now attracting the attention of biochemists. In the present study, p-aminoacetophenone-based Schiff base derivative of triethylenetetramine is prepared. The presence of both keto & amino group is expected to enhance the synthetic application of the derivative. Here the synthesis, spectral characterization and the dielectric constant study of a Schiff base from p-aminoacetophenone and triethylenetetramine are presented. The electronic absorption spectral changes on ascorbic acid mixed Schiff base are reported. The synthesized Schiff base have free and active >NH, -NH2 and >C=O groups and is expected to have interactions with ascorbic acid through either hydrogen bonding or chemical interactions.
