A new copolymer of 3,4-ethylenedioxythiophene (EDOT) and 5-(2-ethylhexyl)-1,3-bis(9-methyl-9H-carbazol-3-yl)-5H-thieno[3,4-c]pyrrole-4,6-dione (CzPDICz) was electrochemically synthesized using different monomer feed ratios. The resulting copolymer films were investigated in terms of their electrochemical and electro-optical behaviors. Properties of the obtained copolymer films through different monomer feed ratios were compared to each other and to individual poly(ethylenedioxythiophene; PEDOT) and homopolymer of CzPDICz in order to observe the differences in the properties with respect to PEDOT and P(CzPDICz). Copolymers exhibited well adherence on the electrode surface with having non-diffusional redox process. The monomer feed ratios were prepared as 9:1; 4:1, and 1:1 (EDOT:CzPDICz) and changes in the electrochemical and spectroelectrochemical behavior were noted with increasing CzPDICz ratio in the monomer mixture. Although no appreciable change in the optical band gap values of the copolymers was noted as compared to PEDOT, the neutral blue copolymers exhibited grayish color in their semi-oxidized states and transparent green in their fully oxidized states.

Synthesis, characterization and electrochromic properties of conducting copolymers of 3-[(3-thienylcarbonyl)oxy]-2,2-bis{[(3-thienylcarbonyl)oxy]}propyl 3-thiophene carboxylate with thiophene and pyrrole
Bulut, U; Yilmaz, F; Yagci, Y; Toppare, Levent Kamil (Elsevier BV, 2004-01-01)
3-[(3-Thienylcarbonyl)oxy]-2,2-bis{[(3-thienylcarbonyl)oxy]}propyl 3-thiophene carboxylate (TOTPT) was synthesized by the reaction of 3-thionylcarbonyl chloride with pentaerythritol, it was electrochemically polymerized with either thiophene or pyrrole by using tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte in acetonitrile (AN). Characterization of the resulting copolymers was carried out by FTIR spectroscopy, cyclic voltammetry, thermal gravimetry analysis (TGA), differential sc...
Synthesis and mesophase properties of block and random co-polymers of electroactive and liquid crystalline monomers
Yilmaz, F; Kasapoglu, F; Hepuzer, Y; Yagci, Y; Toppare, Levent Kamil; Fernandes, EG; Galli, G (Informa UK Limited, 2005-01-01)
Homo-polymers and random co-polymers of electroactive and liquid crystalline monomers, namely 3-thienylmethyl methacrylate (MTM) and 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (LC6), were prepared by conventional free radical polymerization. Block co-polymers of MTM and LC6 were also synthesized by using the 1,1-diphenylethene (DPE) method. The obtained random and block co-polymers exhibited liquid crystal behavior depending on the content of the LC6 units. It was found that microphase separation of the polym...
Synthesis and characterization of conducting graft copolymers based on oligophenols
Sahmetlioglu, Ertugrul; Arikan, Ufuk; Toppare, Levent Kamil; Yuruk, Huseyin; Mart, Hasan (Informa UK Limited, 2006-10-01)
Oligo-2-aminophenol (OAF) was synthesized with oxidative polycondensation of 2-aminophenol and hydrogen peroxide in an aqueous alkaline medium at 80 degrees C. Oligo-2-aminophenol with thiophene side groups (TOAF) was obtained by the reaction of OAF and thiophene-3-acetic acid. Graft copolymers of TOAF and pyrrole were synthesized by electrochemical polymerization in p-toluene sulfonic acid (PTSA)/water medium. Characterization of the graft copolymer (TOAF-g-Py), was carried out by combination of techniques...
Synthesis and characterization of thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester and its conducting polymers
BINGÖL, Bahar; GÜNER, Yusuf; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2005-08-01)
Thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) monomer was synthesized via reaction of thiophen-3-yl acetyl chloride with 4-pyrrol-1-yl phenol. Homopolymers were achieved by using electrochemical and chemical polymerization techniques. Copolymers of TAPE with bithiophene or pyrrole were synthesized by potentiostatic electrochemical polymerization in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte couple. The chemical structures were confirmed by both Nuclear Magnet...
Synthesis, characterization, and electrochromic properties of conducting copolymers of 2-[(3-thienylcarbonyl)oxy]ethyl 3-thiophene carboxylate with thiophene and pyrrole
Bulut, U; Alkan, S; Yilmaz, F; Yagci, Y; Toppare, Levent Kamil (Informa UK Limited, 2004-07-01)
2-[(3-Thienylcarbonyl)oxy]ethyl 3-thiophene carboxylate (TOET) was synthesized via the reaction of 3-thionylcarboxylic acid with ethylene glycol, and electrochemically polymerized with thiophene (Th) and pyrrole (Py) by using tetrabutylannnonium tetrafluoroborate (TBAFB) as the supporting electrolyte in acetonitrile (ACN). Characterization of the resulting copolymers were performed via cyclic voltammetry, FTIR, and scanning electron microscopy (SEM). Electrical conductivities are measured by the four-probe ...
