Electrochemical synthesis of crowned conducting polymers : nature of radical cations in polymerization and mechanism of conductivity
Cihaner, Atilla; Önal, Ahmet Muhtar; Department of Chemistry (2004)
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 solvent and tetrabutylammonium tetrafluoroborate (TBABF4) or tetrabutylammonium hexafluorophosphate (TBAPF6) 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 polymers h...
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 ...
Electrochemical properties of a new star-shaped pyrrole monomer and its electrochromic applications
Ak, Metin; Ak, Mine Sulak; Toppare, Levent Kamil (Wiley, 2006-08-02)
A new monomer, 2,4,6-tris(4-(1H-pyrroI-1-yl) phenoxy)-1,3,5-triazine (Tria-Py) was synthesized via the reaction,of 4-(1H-pyrrol-1-yl)phenol with 2,4,6-trichloro-1,3, 5-triazine. It was electrochemically polymerized in a dichloromethane/acetonitrile solvent mixture. The polymer P(Tria-Py) was characterized via CV, FTIR, SEM and uv-vis spectroscopy. Spectroelectrochemical analysis revealed electronic transitions at 346, 508 and 665, nm, revealing pi to pi* transitions, and polaron and bipolaton band formation...
Electrochemical behaviour and electrochemical polymerization of fluoro-substituted anilines
Cihaner, A; Önal, Ahmet Muhtar (2002-08-01)
The electrochemical behaviour of three fluoro-substituted aniline monomers, 2-fluoroaniline (2FAN), 3-fluoroaniline (3FAN) and 4-fluoroaniline (4FAN), was investigated in aqueous acidic and organic media by means of cyclic voltammetry (CV) studies. Constant potential electrolysis (CPE) of the monomers in acetonitrile-water mixture (1: 1 by volume) using NaClO4 as supporting electrolyte yielded soluble polymers. The mechanism of electrochemical polymerization was investigated using in situ electron spin reso...
Electrochemical Formation of Brazing Alloys on Metal Substrates
Ulu, F.; Karakaya, İshak; Demirci, G.; ERDOĞAN, MUSTAFA (2013-11-01)
CusilTM is a eutectic brazing alloy of 72% silver, 28% copper composition; used to join different materials. The large difference between the standard reduction potentials of silver (0.799V) and copper (0.337V) makes their electrochemical codeposition difficult. A complex ion bath containing KAg(CN)2, CuCN and KCN was used to bring the reduction potentials closer together. The effect of electrolyte concentration on composition and microstructure of electrodeposited Ag-Cu films was investigated at 25oC. A cu...
