Controlled potential electrolysis was employed to accomplish homopolymerization of maleic anhydride, by direct electron transfer. The solvent used in the polymerization studies was acetonitrile-dimethylformamide mixture (1:1) with the supporting electrolyte tetrabutylammonium tetra fluoroborate. A brown paramagnetic polymer was obtained from the catholyte, upon electroreduction of monomer.

Electrosynthesis of polyfuran in acetonitrile-boron trifluoride-ethyl ether mixture and its device application Tirkeş, Süha; Önal, Ahmet Muhtar (Wiley, 2007-01-15) Electrochemical polymerization of furan was achieved in acetonitrile/boron trifluoride/ethyl ether (CH3 CN/BF3/EE) mixture in the presence of tetrabutylammonium tetrafluoroborate via constant potential electrolysis at 1.4 V versus Ag/AgCl. Electrochemical behavior of furan was investigated in the same solvent mixture of varying ratios, utilizing cyclic voltammetry. Free-standing polyfuran (PFu) films were obtained in CH3CN/BF3/EE mixture (2/4/4; v/v/v) and characterized using FTIR spectroscopic technique. S...
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 '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...
Electrochemical polymerization and characterization of polyether-substituted aniline derivatives Tirkeş, Süha; Oenal, Ahmet M. (Wiley, 2007-08-01) New compounds consisting of aniline units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis and cyclic voltammetry in an aqueous solution containing 3.0 moI L-1 H2SO4. Chemical polymerization was carried out using (NH4)(2)S2O8 as oxidizing agent. It was found that both methods gave the same polymer product without any cleavage of the polyether bridge between aniline rings. The polymers were characterized using the Fou...
