    Electrochemical polymerization of 2-aminothiazole
    (Springer, 2011) Ciftci, Hakan; Testereci, Hasan Nur; Oktem, Zeki
    Electrochemical polymerization of 2-aminothiazole (AT) was studied in acetonitrile with tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte via constant potential electrolysis (CPE). The redox behavior of AT was investigated in the same solvent-electrolyte couple by cyclic voltammetry, CV. CPE of AT produced a soluble conducting polymer on the electrode surface. The effects of temperature, monomer concentration and polymerization time on the rate of electrochemical polymerization were also studied. The structural analyses of the polymer were carried out by H-1-NMR, FTIR and UV-VIS spectroscopies and elemental analysis. Thermal properties were studied by DSC and TGA. Conductivity measurements were carried out by four-probe technique and the number average molecular weight, M (n), of the polymer was determined by cryoscopy.

    Electrochemical polymerization of 4-allylanisole
    (Pergamon-Elsevier Science Ltd, 2001) Cihaner, Atilla; Testereci, Hasan Nur; Önal, Ahmet M.
    Electrochemical polymerization of 3-allylanisole (4AA). via constant potential electrolysis, has been investigated in acetonitrile using two different supporting electrolytes. Redox behavior of the monomer was also studied in the same solvent-electrolyte couples at room temperature. Electrochemical polymerization of the monomer yielded insoluble polymer films on the electrode surface, which bears a very low conductivity, together with the low molecular weight polymers in the bulk of the solution. The decrease in the monomer concentration, during the electrochemical polymerization. was monitored by taking the cyclic voltammogram of the electrolysis solution. The effect of temperature on the rate of electrochemical polymerization was: also studied. The polymers were characterized by taking the H-1-NMR and FTIR spectra. Molecular weight of the soluble polymer was determined by vapor pressure osmometry. Thermal analysis of the polymer film and soluble polymer were done by DSC. (C) 2001 Elsevier Science Ltd.

    Polymers from renewable resources: synthesis and characterization of poly(2,5-dihydro-2,5-dimethoxy furan)
    (Scientific Technical Research Council Turkey-Tubitak, 2012) Ciftci, Hakan; Oktem, Zeki; Testereci, Hasan Nur
    The cationic polymerization of cis, trans-2,5-dihydro-2,5-dimethoxy furan (DHMF) was studied in the presence of HClO4, in acetonitrile. Different reaction parameters were investigated such as initiator concentration and temperature with duration. Obtained polymers were soluble in dimethylsulfoxide (DMSO) and dimethylformamide (DMF) and the M-n value was calculated as 2700 g/mol by cryoscopy. The FT-IR and H-1-NMR results indicate that the polymerization proceeds via ring opening. Thermal properties were studied by DSC and TGA.

    Preconcentration and electroanalysis of silver at pt electrode modified with poly(2-aminothiazole)
    (Maik Nauka/Interperiodica/Springer, 2013) Ciftci, Hakan; Testereci, Hasan Nur; Oktem, Zeki
    Conducting poly(2-aminothiazole) (PAT) films were electrodeposited on a platinum disc electrode surface by constant potential electrolysis of 2-aminothiazole (AT) for the stripping voltammetric determination of Ag(I). Ag(I) was preconcentrated on the polymer matrix by dipping the modified Pt electrode (PAT-Pt electrode) into Ag(I)(aq) solution. Effects of the film thickness, reduction potential, pH, preconcentration time, Ag(I) concentration and the interference of some other metal ions on the oxidation peak current of silver were studied. Cu(II) interference observed to be significant for the stripping voltammetric determination of Ag(I). The detection limit was calculated on the basis of signal to noise ratio of 3 as 2 x 10(-7) mol L-1.

    Ring opening polymerization of 2-aminothiazole with iron(III) chloride
    (Springer, 2013) Ciftci, Hakan; Testereci, Hasan Nur; Oktem, Zeki
    Poly(2-aminothiazole), PAT, was synthesized by the chemical polymerization of 2-aminothiazole, AT, with FeCl3 center dot 6H(2)O in 1,4-dioxane. The effect of temperature, monomer, and initiator concentration and polymerization time on the rate of polymerization was studied. The structural analysis of the polymer was carried out by elemental analysis and H-1-NMR, FTIR, and UV-VIS spectroscopies. Thermal properties were studied by DSC and TGA. Conductivity measurements were carried out by four-probe technique and the number average molecular weight, M (n), of the polymer was determined by cryoscopy.
