A monomer 2,5-di(thiophen-2-yl)-1-p-tolyl-1H-pyrrole was synthesized via reaction of 1,4-di(2-thienyl)-1,4-butanedione and p-toluidine in the presence of catalytical amount of p-toluenesulfonic acid. Chemical polymerization of the monomer yielded a soluble polymer. The average molecular weight was determined by gel permeation chromatography as number average molecular weight (Mn) 2.5 x 10(3) g/mol. The monomer was also electrochemically polymerized in the presence of LiClO4, NaClO4 (1:1) as the supporting electrolyte in acetonitrile. Cyclic Voltammetry, Fourier Transform Infra Red, Nuclear Magnetic Resonance, Scanning Electron Microscopy and Ultraviolet-Visible Spectroscopy were employed for the characterization of the polymer. Spectroelectrochemistry analysis of homopolymer revealed an electronic transition at 428 nm which corresponds to pi-pi* transition. Switching ability of the homopolymer was evaluated by kinetic studies upon measuring the percent transmittance (%T) at the maximum contrast point, indicating that poly(2,5-di(thiophen-2-yl)-l-p-tolyl-IH-pyrrole) is a suitable material for electrochromic devices.

An integrated process for partial oxidation of alkanes Zhou, XP; Yılmaz, Ayşen; Yilmaz, GA; Lorkovic, YM; Laverman, LE; Weiss, M; Sherman, JH; McFarland, EW; Stucky, GD; Ford, PC (Royal Society of Chemistry (RSC), 2003-09-21) The partial oxidation of alkanes via bromination followed by the reaction with solid metal oxide mixtures (MO) is shown to give an array of products that can be tuned by varying the MO and the reaction conditions.
Electrochemical polymerization of 9-fluorenecarboxylic acid and its electrochromic device application Bezgin, Buket; CİHANER, ATİLLA; Önal, Ahmet Muhtar (Elsevier BV, 2008-09-01) Poly(9-fluorenecarboxylic acid) (PFCA) was synthesized by electrochemical oxidation of 9-fluorenecarboxylic acid (FCA) using a mixture of nitromethane and boron trifluoride diethyl etherate as the solvent and tetrabutylammonium tetrafluoroborate as the supporting electrolyte. An insoluble and conducting brownish-orange film was deposited on the electrode surface, both during repetitive cycling and constant potential electrolysis at 1.15 V. Characterization of the polymer film has been carried out using Four...
A neutral state yellow to navy polymer electrochrome with pyrene scaffold Icli-Ozkut, Merve; Oztas, Zahide; Algi, Fatih; CİHANER, ATİLLA (Elsevier BV, 2011-09-01) A new pyrene based soluble polymer, namely poly(3,3-didecyl-6-(1-(3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4] dioxepin-6-yl) pyren-6-yl)-3,4-dihydro-2H-thieno[3,4-b][1,4] dioxepine), P5, which is synthesized by both chemical and electrochemical methods, is highlighted. The polymer shows both electrochromic and fluorescent properties (the emission of yellow (545 nm) and yellowish green light (524 nm) in solid state and in THF solution, respectively). It is noteworthy that P5 has a specific optical band gap...
Direct enantioselective aldol reactions catalyzed by a proline-thiourea host-guest complex Reis, Oemer; Eymur, Serkan; Reis, Barbaros; Demir, Ayhan Sıtkı (Royal Society of Chemistry (RSC), 2009-01-01) Proline-thiourea host-guest complex-catalyzed direct enantioselective aldol reactions have been developed, in which the catalytic activities were evaluated in the direct asymmetric aldol reactions of various aromatic aldehydes and cyclohexanone.
Sodium, ammonium, calcium, and magnesium forms of zeolite Y for the adsorption of glucose and fructose from aqueous solutions Heper, Misket; Türker, Burhan Lemi; Kincal, N. Suzan (Elsevier BV, 2007-02-01) The kinetics of adsorption by sodium, ammonium, calcium and magnesium forms of zeolite Y from aqueous solutions containing 25% w/v of either one or an equimolar mixture of glucose (G) and fructose (F) have been studied batch-wise at 50 degrees C. The adsorption of aqueous pure G was fast, while that of aqueous pure F depended on the cationic form, approaching that of G on the Mg-Y, and slowing down in the sequence of Mg2+ > NH4+ > Ca-2(+) > Na+ of the cations. The adsorption behavior from solutions containi...
