Thiophene-containing Schiff base polymers: synthesis, characterization, and anti-bacterial properties
We synthesized the Schiff bases and their polymers, which contain thiophene units. For the synthesis process, first, hydroxynaphthalene di- and triol-derived Schiff bases that are abbreviated as (A1) and (A2) were prepared by a common condensation reaction. Second, their polymers named as B1 and B2...

in an aqueous alkaline medium. The new polymeric structures that are abbreviated as B1-S and B2-S, containing thiophene groups, were synthesized by HBr elimination using B1 and B2 polymers. The characterization processes of the synthesized products were carried out using spectroscopic techniques such as FTIR, UV–Vis,

C NMR, TG-DTG analysis, and MALDI-TOF MS. According to the TG analysis results, except for A2, the thermal stabilities of the other compounds were good since they left about 50% residue at 800°C. SEM images of the compounds were recorded at different sizes, and also they were found to be quite different from each other. For example, A1 was like a ball. Additionally, A1, A2, B1, B2, B1-S, and B2-S were tested for their anti-bacterial activities against some bacteria types. Minimum inhibitory concentration (MIC) method was used for the anti-bacterial activity tests. The MIC test results showed that the synthesized polymers could be used as antimicrobial agents for surfaces with
P. vulgaris
NRRL-B-123 bacteria at lower concentrations such as 15.625 and 31.25 µg/mL.
