Graft copolymers of poly(vinyl alcohol) with thiophene side-groups and pyrrole were synthesized by electrochemical polymerization methods. Poly(vinyl alcohol) with thiophene side-groups (PVATh) was obtained from the reaction between poly(vinyl alcohol) (PVA) and thiophene-3-acetic acid. The syntheses of copolymers Of PVATh and pyrrole were achieved electrochemically by using three different supporting electrolytes, p-toluene sulfonic acid (PTSA), sodium dodecyl sulfate (SDS) and tetrabutylammonium tetrafluoroborate (TBAFB). Characterization of PVATh and graft copolymers was performed by a combination of techniques including cyclic voltammetry, scanning electron microscopy, thermal gravimetry, differential scanning calorimetry, size-exclusion chromatography, H-1 NMR and FT-IR. The conductivities were measured by the four-probe technique. (C) 2004 Society of Chemical Industry.


Synthesis and characterization of a new copolymer of PTSA doped polypyrrole
Levent, A.; Hacaloğlu, Jale; Toppare, Levent Kamil; Yagci, Y. (2003-04-04)
In this work poly(2-methylbutyl 2-(3-thienyl)acetate was prepared by galvanostatic polymerization of (S)-2-methylbutyl 2-(3-thienyl) acetate. Polypyrrole was electrochemically polymerized on a poly(2-methylbutyl 2-(3-thienyl)-acetate) coated anode through the thiophene moities of the matrix polymer. Direct insertion probe pyrolysis MS and Curie point pyrolysis GCMS techniques were utilized for structural and thermal characterizations.
Synthesis and characterization of a bifunctional amido-thiophene monomer and its copolymer with thiophene and electrochemical properties
AK, M; Çırpan, Ali; Yılmaz, Fatih; YAGCI, Y; Toppare, Levent Kamil (2005-05-01)
A bifunctional amido-thiophene namely hexamethylene (bis-3-thiophene acetamide) (HMTA) was synthesized by the reaction of 3-thiophene acetic acid with hexamethylene diamine. Copolymerization in the presence of thiophene was achieved electrochemically in tetrabutylammonium tetrafluoroborate/acetonitrile (TBAFB/AN). Spectroelectro-chemical analysis of the resulting copolymer [P(HMTA-co-Th)] reflected electronic transitions at 505 nm, 740 nm and similar to 1000 nm, revealing pi to pi* transition, polaron and b...
Synthesis and characterization of conducting copolymers of menthyl ester of 3-thiophene acetic acid with pyrrole
Kiralp, S; Alkan, S; Toppare, Levent Kamil; Cianga, I; Yagci, Y (2003-01-01)
A new thiophene derivative containing menthyl group (MM) was synthesized and polymerized via chemical and electrochemical (constant current) methods. Polymers obtained and MM itself were used to synthesize copolymers with pyrrole under conditions of constant potential electrolyses. Cyclic voltammetry (CV), thermal analysis (DSC, TGA) and scanning electron microscopy (SEM) analyses were performed for the characterization of samples.
Synthesis of n-(2-propylphenyl) substituted chiral amino alcohols and their usage in enantioselective diethylzinc addition reactions
Günler, Zeynep İnci; Tanyeli, Cihangir; Department of Chemistry (2011)
IChiral 1,2-amino alcohols were synthesized via newly developed “intramolecular unsaturation transfer” using cyclohexanone, propargyl bromide, and various chiral amino alcohols as starting components. These amino alcohols can be potential chiral ligands for many asymmetric transformation reactions. Therefore, their effectiveness as chiral ligands in diethylzinc addition to benzaldehyde and N-diphenylphosphinoyl imines were tested. Various parameters including temperature, solvent, ligand amount etc. were sc...
Synthesis and characterization of conducting copolymers of thiophene functionalized monomers and polymers
Papila, Özge; Toppare, Levent Kamil; Department of Chemistry (2003)
Synthesis and characterization of conducting copolymers were achieved by using thiophene end-funtionalized TEMPO initiated polystyrene (PS), decanoic acid dithiophen-3yl-me1hyl ester (DTME) and octanoic acid thiophen-3yl-methyl ester (OTME). Redox behavior of polymer and monomers were done by Cyclic Voltammetry (CV). Structural and characterization of samples were carried out by XB., 13C Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR). Thermal analyses of resultant conduc...
