Copolymer of aniline and triethylene glycol bis(o-aminophenyl) ether was synthesized by constant potential electrolysis. Cyclic voltammogram of the copolymer films recorded in the monomer-free electrolytic solution revealed that the redox behavior of the films approaches to that of poly(triethylene glycol bis(o-aminophenyl) ether) with increasing amount of triethylene glycol bis(o-aminophenyl) in the feed ratio. Copolymerization was investigated by in situ recording the changes in the electronic absorption spectrum during electrolysis. The free standing copolymer film was characterized utilizing Fourier transform infrared spectrometer, and spectroelectrochemical behavior of the copolymer was investigated via in situ UV-vis spectroscopic technique. Besides the electron spin resonance study of the copolymer film, the different morphologies of the polymers were examined by scanning electron microscopy and the copolymerization was confirmed. The temperature dependence conductivity of the copolymer film was measured by four-probe technique in the temperature range of 100-300 K, and the calculated parameters showed that conduction mechanism fits to variable range hopping.

ELECTROLYSIS OF MGCL2 WITH A TOP INSERTED ANODE AND AN MG PB CATHODE GUDEN, M; Karakaya, İshak (Springer Science and Business Media LLC, 1994-08-01) High energy consumption in the production of magnesium by molten salt electrolysis is mainly due to the recombination of magnesium and chlorine. The large interelectrode distance used, in conventional techniques, to reduce the extent of 'back reaction', results in a significant potential drop. A laboratory cell that enables the operation with smaller interelectrode distance and easy separation of electrode products has been used to study electrolytic magnesium production. The cell features a top inserted gr...
Spectroelectrochemical investigation of the anodic oxidation of dibenzo-18-crown-6 Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2004-10-01) Poly(dibenzo-18-crown-6) (poly-DB18C6) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as the solvent and tetrabutylammonium tetrafluoroborate (TBABF(4)) or tetrabutylammonium hexafluorophosphate (TBAPF(6)) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in situ ESR and in situ UV-Vis spectroscopic techniques. Spectroelectrochemical (SPEL), properties and thermal analysis of the resulting po...
Electrochemical and optical properties of novel terthienyl based azobenzene, coumarine and fluorescein containing polymers: Multicolored electrochromic polymers Yigit, Deniz; Udum, Yasemin Arslan; GÜLLÜ, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2014-01-01) Three electroactive terthienyl based monomers, namely 1-phenyl-2-[4-(2,2':5',2 ''-terthien-3'-ylmethoxy)phenyl]diazene (TTAz), 4-(2,2':5',2 ''-terthien-3'-ylmethoxy)-2H-chromen-2-one (TTCo) and methyl 2-[3-oxo-6-(2,2':5',2 ''-terthien-3'-ylmethoxy)-3H-xanthen-9-yl] benzoate (TTFlo), were synthesized with good yields and their conducting polymers were electrochemically prepared on ITO electrode surfaces. The effect of chromophore type on electrochemical and optical properties of the polymers was investigated...
Synthesis and polymerization of 2-and 3-substituted thiophene derivatives linked by polyether bridges Tirkeş, Süha; Önal, Ahmet Muhtar (Elsevier BV, 2004-11-15) New compounds consisting of 2- and 3-thienyl units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis (CPE) in an electrolytic solution containing 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)) dissolved in CH3CN. 2-Thienyl monomers (I and II), but not 3-thienyl monomers (III and IV), were also polymerized via chemical oxidation, which yielded broken pi-conjugated polymer products. The polymers were characteri...
Electrochemical investigation of copper-DTPI interactions Hicyilmaz, C; Altun, Naci Emre (Springer Science and Business Media LLC, 2006-05-01) The electrochemical behavior of copper in the absence and presence of a dithiophosphinate type collector, sodium diisobuthyldithiophosphinate (NaDTPI), was determined to investigate the interactions between a copper surface and NaDTPI as a function of pulp potential (Eh) and pH. The electrochemical studies were performed by Cyclic Voltammetry (CV) in the -355 to +1550 mV (SHE) potential range and at different pHs from slightly acidic to strongly alkaline conditions. The electrochemical studies were carried ...
