Dual polymer electrochromic devices (ECDs) composed of electrochemically deposited conducting copolymers of thiophene-functionalized monomers, 2-[(3-thienylcarbonyl)oxy] ethyl 3-thiophene carboxylate (TOET), 2,3-bis-[(3-thienylcarbonyl)oxy]propyl 3-thiophene carboxylate (TOPT), and 3-[(3-thienylcarbonyl)oxy]-2,2-bis-[(3-thienylcarbonyl)oxy]propyl 3-thiophene carboxylate (TOTPT), and polyethylene dioxythiophene (PEDOT) as the counter part were constructed with tetrabutylammonium tetrafluoroborate (TBAFB) doped gelled poly(methyl methacrylate) (PMMA) and evaluated. An electrochromic device with the following configuration was assembled - indium tin oxide (ITO)-coated glass /conducting copolymer parallel to gel electrolyte parallel to PEDOT/ITO. Spectroelectrochemistry, electrochromic switching, stability and open-circuit memory of the devices were examined.

ELECTRICALLY CONDUCTIVE POLY(METHYL METHACRYLATE-G-PYRROLE) VIA CHEMICAL OXIDATIVE POLYMERIZATION STANKE, D; HALLENSLEBEN, ML; Toppare, Levent Kamil (Elsevier BV, 1993-03-22) Methyl methacrylate (MMA) and 2-bromoethyl methacrylate (BEMA) were copolymerized and the reactivity ratios of the monomers were determined. A pyrrole moiety was introduced into the copolymer via polymer analogous reaction and grafting between this molecule and pyrrole was achieved by chemical oxidative polymerization of pyrrole with iron-(III) chloride. Conductivities of 10(-2) S/cm were measured.
Electrochemical and optical properties of 5,6-bis(octyloxy)-2,1,3 benzooxadiazole containing low band gap polymers Goker, Seza; Hizalan, Gonul; Udum, Yasemin Arslan; Toppare, Levent Kamil (Elsevier BV, 2014-05-01) Benzooxadiazole containing three monomers; 5,6-bis(octyloxy)-4,7-bis(4-hexylthiophen-2-yl)-2,1,3-benzoxadiazole (BOHT), 5,6-bis(octyloxy)-4,7-di-2-thienyl-2,1,3-benzoxadiazole (BODT) and 5,6-bis(octyloxy)-4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2,1,3-benzoxadiazole (BODHT) were synthesized via Stille coupling reaction. Their electrochemical polymerizations were carried out on ITO coated glass slides in a three electrode system. Electrochemical, spectral and kinetic results were given in detail and...
Conducting polymers of succinic acid bis-(2-thiophen-3-yl-ethyl)ester and their electrochromic properties SACAN, L; Çırpan, Ali; CAMURLU, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01) The homopolymer and copolymer of succinic acid bis-(2-thiophen-3-yl-ethyl)ester with thiophene were achieved via constant potential electrolysis in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, and acetonitrile/borontrifluoride ethylether (ACN/BFEE) (10:2 v/v) solvent mixture. The characterizations of both homopolymer (PSATE) and copolymer P(SATE-co-Th) were achieved by various techniques including cyclic voltammetry (CV), Fr-IR, scanning electron microscopy (SEM) and U...
Electrochemical preparation and characterization of carbon fiber reinforced poly (dimethyl siloxane)/polythiophene composites: electrical, thermal and mechanical properties Sankir, M; Kucukyavuz, S; Kucukyavuz, Z (Elsevier BV, 2002-05-10) A series of polydimethylsiloxane (PDMS)/polythiophene (Pth)/carbon fiber (CF) composites was synthesized by electrochemical polymerization using tetrabutylammoniumtetrafluoroborate (TBAFB) as supporting electrolyte and acetonitrile as solvent. Composites were characterized by TGA, SEM, and mechanical tests and conductivity measurements. Conductivities of composites were in the range of 25 S/cm. SEM studies show that CF were coated by PDMS/Pth matrix and well oriented in the matrix. In mechanical tests it ha...
Benzyl substituted benzotriazole containing conjugated polymers: Effect of position of the substituent on electrochromic properties Yigitsoy, Basak; Karim, S. M. Abdul; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2010-12-01) New classes of EDOT coupled-benzotriazole bearing pi-conjugated monomers containing benzyl units on electron-withdrawing benzotriazole moiety were synthesized. The effect of structural differences on electrochemical and optoelectronic properties of the resulting polymers (PBBTES and PBBTEA) was investigated. The results showed that the insertion of benzyl substituent to benzotriazole from different positions changes the electronic structure of polymer which results in completely different electrochemical an...
