“…The highest value of PCE, i.e., 0.31%, was found for polyazomethine synthesised from 2,5-thiophenedicarboxaldehyde and 2,7-diaminofluorene [68]. For polyazomethines obtained from 3,3 0 -dimethoxybenzidine and 2,2 0 :5 0 ,2″-terthiophene-5,5″-dicarboxaldehyde or 2,5-thiophenedicarboxaldehyde, PCE values in the range of 0.01-0.52%, depending on the dialdehyde applied and the architecture of the device, were found [69]. The highest value of PCE, i.e., 0.52%, was obtained for the solar cell with the active layer based on PC 71 BM and polyazomethines with three thiophene rings per unit [69].…”

Five new linear Schiff base polymers having azomethine structures, ether linkages and extended aliphatic chain lengths with flexible spacers were synthesized by polycondensation of dialdehyde (monomer) with aliphatic and aromatic diamines. The formation yields of monomer and polymers were obtained within 75-92%. The polymers with flexible spacers of n-hexane were somewhat soluble in acetone, chloroform, THF, DMF and DMSO on heating. The monomer and polymers were characterized by melting point, elemental microanalysis, FT-IR, 1 HNMR, UV-Vis spectroscopy, thermogravimetry (TG), differential thermal analysis (DTA), fluorescence emission, scanning electron microscopy (SEM) and viscosities measurement of their dilute solutions. The studies supported formation of the monomer and polymers and on the basis of these studies their structures have been assigned. The synthesized polymers were tested for their antibacterial and antifungal activities.

A novel polyphenol with azomethine group, Poly(2‐[[4‐(dimethylamino)benzylidene]amino]phenol) P(2‐DBAP), was synthesized by oxidative polycondensation of 2‐[[4‐(dimethylamino)benzylidene]amino]phenol) (2‐DBAP) using NaOCl, H2O2, and O2 oxidants in aqueous alkaline medium. The effects of oxidant type and concentration, monomer concentration and polymerization temperature and time on yield and molecular weight distribution of P(2‐DBAP) were investigated. The structures of 2‐DBAP and P(2‐DBAP) were confirmed by UV‐Vis, FTIR, and 1HNMR techniques. Thermal behavior of the polymer was also analyzed by TG‐DTG techniques. Electrical conductivity value of P(2‐DBAP) which was doped with iodine for 24 hr at 60°C was measured as 7 × 10−2 S/cm by increasing 1010 fold compared with its undoped form. This conductivity level is the highest value reported in the literature for polyphenols containing azomethine group. Additionally, antimicrobial activities of 2‐DBAP and P(2‐DBAP) were tested against Sarcina lutea, Enterobacter aerogenes, Escherichia coli, Enterococcus Feacalis, Klebsiella pneumoniae, and Bacillus subtilis bacteria and Candida albicans and Saccharomyces cerevisiae fungi.
