“…a, respectively. The current responses were directly proportional to the scan rate, indicating that the PPy–ZnS and PEDOT–ZnS composite films were electroactive and well adhered to the electrode . The scan rates for the anodic and cathodic peak currents show a linear dependence as a function of the scan rate as illustrated in inserted figures in Fig.…”

Polypyrrole-zinc sulfide (PPy-ZnS) and poly(3,4-ethylenedioxythiophene)-zinc sulfide (PEDOT-ZnS) composite films were synthesized and characterized. Their electrochemical behaviors were investigated. The synthesis of PPy-ZnS and PEDOT-ZnS composite films was carried out by electropolymerization of pyrrole and 3,4-ethylenedioxythiophene in the presence of ZnS nanoparticles dispersed in the electrolytic solution. The structures of the PPy-ZnS and PEDOT-ZnS composite films were characterized by the use of scanning electron microscopy, atomic force microscopy, and UV-vis spectroscopy. Cyclic voltammetry was used to determine the electrochemical behavior of the resulting materials. The Energy Dispersive X-Ray mapping (EDX mapping) method was used to detect the existence of Zn and S ions on PPy-ZnS and the Zn ion on PEDOT-ZnS composite films. A four-probe technique was used to measure the conductivity of PPy-ZnS and PEDOT-ZnS composite films along with PPy and PEDOT. C

Enzymatic oxidative polymerization of a new para‐imine functionalized phenol derivative, 4‐(4‐hydroxybenzylideneamino)benzoic acid (HBBA), using horseradish peroxidase enzyme and hydrogen peroxide oxidizer has been investigated in an equivolume mixture of an organic solvent (acetone, methanol, ethanol, dimethylformamide, 1,4‐dioxane, and tetrahydrofuran) and phosphate buffer (pH = 5.0, 6.0, 6.8, 7.0, 7.2, 8.0, and 9.0) at different temperatures under air for 24 h. The resulting oligomer, oligo(4‐(4‐hydroxybenzylideneamino)benzoic acid) [oligo(HBBA)], was characterized using ultraviolet–visible, Fourier transform infrared (FT‐IR), 1H nuclear magnetic resonance (NMR), cyclic voltammetry, size exclusion chromatography, differential scanning calorimetry, and thermogravimetric analyses. Polymerization involved carbon dioxide and hydrogen elimination from the monomer, and terminal units of the oligomer structure consisted of phenolic hydroxyl (–OH) groups at the ends. The polymer is mainly composed of a mixture of phenylene and oxyphenylene units according to 1H NMR and FT‐IR analyses. Effects of solvent system, temperature and buffer pH on the polymerization have been investigated in respect to the yield and molecular weight (Mn) of the product. The best condition in terms of the highest molecular weight (Mn = 3000 g/mol, DP ~ 15) was achieved in an equivolume mixture of 1,4‐dioxane/pH 5.0 phosphate buffer condition at 35°C. Electrochemical characterization of oligo(HBBA) was investigated at different scan rates. The resulting oligomer has also shown relatively high thermal stability according to thermogravimetric analysis. Copyright © 2015 John Wiley & Sons, Ltd.

Hidrazon fonksiyonlu oligofenol, (E)-2-(1-(2-fenilhidrazon)etil)fenol[FHEF] enzimatik oksidatif polimerizasyon yöntemiyle sentezlenmiştir. Yan zincirinde hidrazon fonksiyonel grubu içeren fenol türevinin enzimatik oksidatif polimerizasyonunda; katalizör olarak Horseradish peroksidaz (HRP) enzimi, yükseltgeyici olarak ise Hidrojen peroksit (H 2 O 2 ) kullanılmıştır. Polimerleşme üzerine reaksiyon sıcaklığı, reaksiyon pH'sı ve çözücü sistemleri gibi değişik parametrelerin etkileri çalışılmıştır. Sentezlenen oligomerin karakterizasyonu nükleer magnetic rezonans ( 1 H ve 13 C NMR), infrared spektroskopisi (FT-IR), jel geçirgenlik kromotoğrafisi (GPC), ultraviyole spektroskopisi (UV-Vis), dönüşümlü voltametri (CV) ve termogravimetrik analiz (TGA/DTA) teknikleri ile yapılmıştır.
