Polymer-Bound Schiff Bases and Their Cr(III) Complexes: Synthesis, Characterization, Antibacterial and Antifungal Evaluation

Abstract

Three novel polymer-bound Schiff bases and their Cr(III) complexes were synthesized from the reaction of polystyrene-A-NH2 with 5-fluoro-2-hydroxybenzaldehyde/5-fluoro-3-chloro-2-hydroxybenzaldehyde/5-fluoro-3-methyl-2-hydroxybenzaldehyde and were characterized by elemental analysis, magnetic susceptibility, IR, H-1 NMR, UV-Vis, TG/DTA analysis. The biological activities of synthesized compounds were screened against some gram-positive bacteria (Bacillus cereus sp., Listeria monocytogenes 4b, Micrococcus luteus, Staphylococcus aureus, Staphylococcus epidermis) with some gram-negative bacteria (Brucella abortus, Escherichia coli, Pseudomonas putida sp., Shigella dysenteria type 10, Salmonella typhi H) and yeast (Candida albicans) by the well-diffusion method.
