Dual type polymer electrochromic devices (ECDs) based on potentiodynamically coated films of octanoic acid 2-thiophen-3-yl-ethyl ester (OTE), decanedioic acid bis-(2-thiophen-3-yl-ethyl) ester (DATE) and ethylene dioxythiophene (EDOT) were constructed. The former two function as anodically coloring layers and the latter as a cathodically coloring layer in between tetrabutylammonium tetrafluoroborate (TBAFB) poly(methylmethacrylate) gel media. The spectroelectrochemistry, switching ability and stability of the devices were investigated by U-V-Vis spectrometry and cyclic voltarnmetry. These devices exhibit low switching voltages (0-1.4 V) and short switching times with reasonable switching stability under atmospheric conditions.

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...
Molecular architecture: Another plausible pathway toward a low band gap polymer Tarkuc, Simge; Udum, Yasemin Arslan; Toppare, Levent Kamil (Elsevier BV, 2010-05-01) A donor-acceptor-donor pi-conjugated monomer (10,13-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)dibenzo[a,c]phenazine (PHED)) composed of bi-EDOT and dibenzo[a,c]phenazine repeat units was synthesized to examine the role of acceptor structure on the electronic and optoelectronic properties of the polymer. The spectroelectrochemical analysis showed that the introduction of electron-accepting unit results in a shift in the onset of the pi-pi* transition towards longer wavelengths. The optical band gap (Eg) f...
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 polymerization of a new low-voltage oxidized thienylenepyrrole-derivative and its electrochromic device application Carbas, Buket Bezgin; KIVRAK, Arif; TEKE, Ecem; Zora, Metin; Önal, Ahmet Muhtar (Elsevier BV, 2014-09-01) Synthesis of a new monomer, 2,5-bis-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1-phenyl-1H-pyrrole (ENE), from pyrrole, iodobenzene and 3,4-ethylenedioxythiophene (EDOT), and its electropolymerization are reported. ENE was oxidized at a low oxidation potential (0.45 V vs. Ag/AgCl) and successfully electropolymerized in acetonitrile containing 0.1 M NaClO4 and LiClO4 electrolyte mixture. The resulting polymer, P(ENE), revealed five distinctive colors upon doping, which indicated that the polymer is multichro...
Multichromic polymers of benzotriazole derivatives: Effect of benzyl substitution Yigitsoy, Basak; Karim, S. M. Abdul; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2011-02-01) Two electroactive monomers 1-benzyl-4,7-di(thiophen-2-yl))-2H-benzo[d][1,2,3]triazole (BBTA) and 2-benzyl-4,7-di(thiophen-2-yl))-2H-benzo[d][1,2,3]triazole (BBTS) were synthesized with satisfactory yields. The effect of substitution site on electrochemical and optical properties was investigated with cyclic voltammetry and spectroelectrochemical studies. Results showed that position of pendant group alters the electronic structure of the resulting polymer causing different optical and electrochemical behavi...
