A novel thermally stable polyazomethine with phenol group, Poly(4-[[4-(dimethylamino)benzylidene] amino]phenol) P(4-DBAP), was synthesized from 4-[[4-(dimethylamino)benzylidene]aminc]phenol) (4-DBAP) in aqueous alkaline medium via oxidative polycondensation with NaOCl, H2O2, and O-2 oxidants. The change of the yield and molecular weight distribution of P(4-DBAP) with oxidant type and concentration, monomer concentration, and polymerization temperature and time were analyzed. The structures of the monomer and polymer were confirmed by UV-Vis, FTIR, H-1-NMR, C-13-NMR and TGA techniques. The conductivity value of the polymer which was doped with iodine vapor for 24 h was reached 3.2 x 10(-5)S/cm and 1.1 x 10(-4) S/cm values by increasing 107 and 108 folds compared to the initial conductivity value at 20 degrees C and 60 degrees C, respectively. This conductivity value which was measured at 20 degrees C is the highest value reported in the literature for polyazomethines having phenol group in such a short time and at low temperature. Moreover, antimicrobial activity test was performed for 4-DBAP and P(4-DBAP) against Sarcina lutea, Enterobacter aerogenes, Escherichia coli, Enterococcus Feacalis, Klebsiella pneumoniae, Bacillus subtilis bacteria, and Candida albicans and Saccharomyces cerevisiae fungi. Although both monomer and polymer showed antibacterial activity, the polymer was more efficient compared to the monomer. (C) 2018 Elsevier B.V. All rights reserved.
