In this study, two new conjugated polymers were synthesized including benzotriazole (BTz) as the acceptor unit and selenophene as the bridge donor segment. These acceptors were coupled with fluorene and carbazole via Suzuki condensation reactions. Electrochemical band gaps were calculated as 2.45 eV for P1 and 2.40 eV for P2. Electrochemical and optical studies of polymers indicate that both polymers are promising candidates for organic solar cell (OSC) and polymer organic light emitting diode (PLED) applications since they have suitable HOMO-LUMO energy levels and appropriate absorption and emission band ranges. Light emitting properties of synthesized polymers were investigated and the highest luminance value was found as 6608 cd/m(2) for P1 at 8V. Photovoltaic properties of polymers were investigated and the optimized device based on P2 showed 1.75% power conversion efficiency for P2 under AM 1.5 G illumination at 100 mW/cm(2).

Immobilization of Tyrosinase in Poly(2-thiophen-3-yl-alkyl ester) Derivatives
ÇAMURLU, PINAR; Kayahan, Senem; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01)
In this study, construction of novel biosensors for the determination of phenolic compound was performed via immobilization of tyrosinase during the electrochemical synthesis of conducting block copolymers of 2-thiophen-3-yl-alkyl ester derivatives with 3,4-ethylenedioxythiophene and synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT). The resultant biosensors were characterized in terms of their maximum reaction rates, Michaelis-Menten constants (Km), temperature and pH stabilities. All the copolymer mat...
Reactive extrusion of poly(ethylene terephthalate)-(ethylene/methyl acrylate/glycidyl methacrylate)-organoclay nanocomposites
Alyamac, Elif; Yılmazer, Ülkü (Wiley, 2007-04-01)
This study was conducted to investigate the effects of component concentrations and addition order of the components on the final properties of ternary nanocomposites composed of poly(ethylene terephthalate), organoclay, and an ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer acting as an impact modifier for PET. In this context, first, the optimum amount of the impact modifier was determined by melt compounding binary PET-terpolymer blends in a corotating twin-screw extruder. The amount...
Conducting copolymers of random and block copolymers of electroactive and liquid crystalline monomers with pyrrole and thiophene
Camurlu, Pinar; Toppare, Levent Kamil; Yilmaz, Faruk; Yagci, Yusuf; Galli, Giancarlo (Informa UK Limited, 2007-03-01)
Block and random copolymers having 3-methyl thienylmethacrylate and 6-(4-cyanobiphenyl-4'-oxy) hexyl acrylate moieties were utilized as precursor polymers in this study. Electrochemical copolymerizations were performed in the presence of thiophene or pyrrole in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) at constant potential. The characterizations were performed by cyclic voltammetry (CV), fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermal gravime...
Dual type complementary colored polymer electrochromic devices based on conducting polymers of poly(hexanedioic acid bis-(2-thiophen-3-yl-ethyl ester)
Camurlu, P; Toppare, Levent Kamil (Informa UK Limited, 2006-03-01)
In this study, dual type polymer electrochromic devices (ECDs) based on homopolymer and copolymer of hexanedioic acid bis-(2-thiophen-3-yl-ethyl ester) with 3,4-ethylene dioxythiophene (EDOT) were constructed, where PEDOT functioned as the cathodically coloring layer. Spectroelectrochemistry, switching ability, stability, open circuit memory and color of the devices were investigated. Results of the kinetic studies showed these devices exhibit switching times around 1.8 s with an optical contrast of 24-25.3...
Polypyrrole grafts synthesized via electrochemical polymerization
Balci, N; Toppare, Levent Kamil; Akbulut, Ural; Stanke, D; Hallensleben, ML (Informa UK Limited, 1998-01-01)
Electrically conducting polypyrrole grafts with poly[(methyl meth acrylate)-co-(2-(N-pyrrolyl) ethyl methacrylate)] (PMMA-co-PEMA) were synthesized by constant potential electrolysis. Cyclic Voltammetry, DSC, TGA, SEM and elemental analysis were used in order to characterize the free standing films. Conductivities of the polymers were measured by a four-probe technique.
