    Electrochemical Synthesis of a Water-Soluble and Self-Doped Polythiophene Derivative
    (VSP BV, 2008) Turac, Ersen; Varol, Ramazan; Ak, Metin; Sahmetlioglu, Ertugrul; Toppare, Levent
    A new monomer, 4-(thiophen-3-yl methyleneamino)benzene sulfonate) (ThSA), was synthesized and characterized. Electrochemical polymerization of ThSA yields a water-soluble and self-doped polymer (PThSA). This polymer was characterized by FT-IR, NMR, DSC, XRD and conductivity measurements.

    Synthesis and Characterization of Conducting Copolymers of Bisphenol A-Diglycidyl Ether with Thiophene Side-Groups and Pyrrole
    (TAYLOR & FRANCIS INC, 2009) Sahmetlioglu, Ertugrul; Varol, Ramazan; Toppare, Levent; Yuruk, Huseyin
    Copolymers of bisphenol A-diglycidyl ether with thiophene side-groups and pyrrole were synthesized by electrochemical polymerization. Bisphenol A-diglycidyl ether with thiophene side-groups (DGEBATh) was obtained from the reaction between bisphenol A-diglycidyl ether (DGEBA) and thiophene-3-acetic acid. The syntheses of copolymers of DGEBATh and pyrrole were achieved electrochemically using three different supporting electrolytes, p-toluene sulfonic acid (PTSA), sodium dodecyl sulfate (SDS) and tetrabutylammonium tetrafluoroborate (TBAFB). Characterizations of DGEBATh and copolymers were performed by combination of techniques including cyclic voltammetry, scanning electron microscopy, gel permeation chromatography, differential scanning calorimetry, 1H-NMR and FT-IR. The conductivities were measured by the four-probe technique.

    Synthesis and characterization of water-soluble oligosalicylaldehyde-sulfanilic acid and its Cu(II), Co(II), Pb(II) complexes
    (JOHN WILEY & SONS INC, 2008) Turac, Ersen; Surme, Yavuz; Sahmetlioglu, Ertugrul; Varol, Ramazan; Narin, Ibrahim; Toppare, Levent
    This work presents the synthesis and characterization of a new water-soluble oligophenol derivative, 4-(2-hydroxybenzylideneamino)benzenesulfanic acid (OSAL-SA) and its metal complexes. The chemical structure of the water-soluble polymer was characterized by nuclear magnetic resonance (H-1 NMR) and Fourier transform infrared (FTIR) spectroscopies and thermogravimetric analyses (TGAs). Pb(II), Cu(II), Co(II) complexes of the polymer were also synthesized in methanol. Characterizations of water insoluble polymer-metal complexes were performed by FTIR, flame atomic absorption spectroscopy, and TGA. he conductivity measurements of OSAL-SA and polymer-metal complexes were carried out by the four-probe technique.
