Polyhaloanilines: poly(4-fluoroaniline) (P4FAN), poly(4-chloroaniline) (P4CAN), and poly(4-bromoaniline) (P4BAN), are synthesized from para-substituted haloaniline monomers; 4-fluoroaniline (4FAN), 4-chloroaniline (4CAN), and 4-bromoaniline (4BAN), respectively, via constant potential electrolysis (CPE) in acetonitrile-water mixture (1:1 v/v) with NaClO4 as supporting electrolyte. Prior to CPE, electrochemical behavior of the monomers were investigated in organic medium utilizing cyclic voltammetry (CV). The course of CPE was monitored using in-situ UV-VIS spectroscopic technique. Characterization of polymer products have been carried out using FT-IR and NMR spectroscopic techniques and thermal behaviors were studied using differential scanning calorimeter (DSC). Polyhaloanilines synthesized by electrochemical oxidation were doped using iodine and the change in the paramagnetic behavior was monitored by ESR, UV-VIS, and FT-IR.

Electrochromic properties of 'Trimeric' thiophene-pyrrole-thiophene derivative grown from electrodeposited 6-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexan-1-amine and its copolymer Tarkuc, Simge; Ak, Metin; Onurhan, Erdal; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01) A centrosymmetric polymer precursor, namely 6-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexan-1-amine (TPHA), was synthesized via a Knorr-Paal reaction using 1,4-di(2-thienyl)-1,4-butanedione and hexane-1,6-diamine. The resultant monomer was characterized by Nuclear Magnetic Resonance (H-1-NMR). Electroactivity of TPHA was investigated via cyclic voltammetry. The electronic structure and the nature of electrochromism in P(TPHA) and its copolymer with EDOT, (P(TPHA-co-EDOT)), were examined via spectroelectrochem...
Electrorheological properties of kaolinite, polyindole, and polyindole/kaolinite composite suspensions Arslan, Yasin; Unal, Halil Ibrahim; Yilmaz, Hasim; Sari, Bekir (Wiley, 2007-06-05) In this study, polyindole (PIN) and polyindole/kaolinite (PIN/KAO) composite were synthesized by free radical polymerization using FeCl3 as an initiator. Average particle sizes (d(50)) of PIN and PIN/KAO composite were determined by dynamic light scattering (DLS) as 7.2 and 6.2 mu m, respectively. The samples were characterized by FTIR, elemental analysis, DSC/TGA and SEM measurements. Suspensions of KAO, PIN, and PIN/KAO composite were prepared in silicone oil (SO) and the sedimentation stabilities were de...
ELECTROINITIATED POLYMERIZATION OF ACRYLAMIDE BY DIRECT ELECTRON-TRANSFER HACIOGLU, B; Akbulut, Ural; Toppare, Levent Kamil (Wiley, 1989-10-01) Electroinitiated polymerization of acrylamide was carried out in acetonitrile–tetrabutylammonium fluoroborate by electrolytic reduction of monomer. It was shown by cyclic voltammetry that direct electron transfer from the cathode to the monomer can be achieved in this solvent–electrolyte system. Reduction peak potentials measured by cyclic voltammetry indicated that sodium salts will interfere with such a mechanism. Since the reduction peak potential of sodium salt and dimethylformamide are found to be lowe...
Electrochemical and Optical Studies of Furan and Thieno[3,2-b]thiophene End Capped Benzotriazole Derivatives AKBASOGLU, Naime; BALAN, Abidin; BARAN, Derya; Çırpan, Ali; Toppare, Levent Kamil (Wiley, 2010-12-01) Two new 2-dodecyl benzotriazole (BTz) based donor-acceptor-donor (DAD) type polymers were synthesized and characterized in terms of their electrochemical and spectral properties. These DAD type polymers were synthesized electrochemically from furan or thieno[3,2-b]thiophene (TT) endcapped BTz monomers. Furan based and thieno[3,2-b]thiophene based monomers showed monomer oxidations at 1.15 and 1.25 V, respectively, which eased the formation of conducting polymer films without overoxidation. Cyclic voltammetr...
Electrochromic properties of copolymer of terephthalic acid bis-(thiophen-3-yl-methyl) thioester with pyrrole Tuerkarslan, Oezlem; Toppare, Levent Kamil (Informa UK Limited, 2007-01-01) Terephthalic acid bis-(thiophen-3-yl-methyl) thioester ( TTMT) was synthesized via the reaction of thiophen-3-yl methanethiol with terephthaloyl dichloride. This 3-functionalized thiophene monomer was polymerized in the presence of pyrrole (Py) upon constant potential application. Spectroelectrochemistry experiments reflected a pi to pi* transition with a band gap energy of 2.4 eV for the copolymer. A dual type electrochromic device (ECD) of P(TTMT-co-Py) and poly(3,4-ethylenedioxythiophene) (PEDOT) was con...
