dc.description.abstractIn the present study, polymers of substitute aromatic diamine were synthesized by oxidative and enzymatic polymerization. Enzymatic polymerization and oxidative polymerization of 3,5-diamino benzoic acid (DIABA) monomer in the presence of HRP (horse radish peroxidase) and H2O2 (hydrogen peroxide) were synthesized PDIABA-E and PDIABBA-O polymers. The structures of DIABA and polymers were confirmed by FT-IR, UV-Vis and NMR measurements. The characterizations of polymers were performed by GPC, TG-DTA, DSC, SEM and fluorescence measurements. Moreover, electrochemical fea-tures of polymers were performed with cyclic voltammetry (CV) measurements. The optical (E-g) and electrochemical (E'(g)) band gap values of PDIABA-O and PDIABA-E were calculated to be as 1.90 and 2.30 eV and 2.38 and 2.52 eV, respectively. The results showed that optical gaps and electrochemical band of PDIABA-E and PDIABBA-O were lower than those of DIABA due to their polyconjugated struc-tures. Quantum yield was calculated as 13% for PDIABA-O. Furthermore, PDIABA-O was used as a sorbent for the removal of methylene blue (MB) from aqueous solution. (C) 2020 Elsevier B.V.
