In this work, 3,4-ethylenedioxythiophene (EDOT) and 1,2,3,4-tetrahydrophenazine based donor-acceptor-donor type monomer (EBE) was synthesized, electropolymerized and the resulting polymer film (P(EBE)) was investigated in terms of its electrochemical and spectroelectrochemical properties. The polymer film showed excellent electrochemical stability upon 1000 switchings by saving almost full of its electroactivity. Moreover, 95% of the optical contrast was maintained after 500 switchings. The optical band gap value was calculated using Tauc Plot method and found as 1.5 eV. P(EBE) film revealed multichromic behaviour between its fully neutral and oxidized states; dark cyanish-green at - 0.8 V, more green at - 0.5 V and transmissive green beyond 0.6 V potentials. Finally, a dual type electrochromic device (ECD) was constructed with P(EBE) and poly(3,4-ethylenedioxythiophene) (PEDOT) films and the spectroelectrochemical behaviour of ECD was depicted.

A new p- and n-dopable selenophene derivative and its electrochromic properties Cetin, Guelben Ardahan; Balan, Abidin; Durmus, Asuman; Günbaş, Emrullah Görkem; Toppare, Levent Kamil (Elsevier BV, 2009-02-01) A novel electrically conducting polymer, poly(2-dodecyl-4,7-di(selenophen-2-yl)benzotriazole) (PSBT), containing selenophene as the strong donor and benzotriazole as the strong acceptor groups was synthesized by electrochemical polymerization. Homopolymerization and copolymerization (in the presence of 3,4-ethylenedioxythiophene (EDOT)) were achieved in acetonitrile/dichloromethane(95/5 v/v) with 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)). The electrochemical and optical properties of homopolym...
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...
Donor acceptor type neutral state green polymer bearing pyrrole as the donor unit Celebi, Selin; Balan, Abidin; Epik, Bugra; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2009-07-01) A new neutral state green polymer, poly (2,3-bis(4-tert-butylphenyl)-5,8-di(1H-pyrrol-2-yl) quinoxaline) (PTBPPQ) was synthesized and its potential use as an electrochromic material was investigated. Spectroelectrochemistry studies showed that polymer reveals two distinct absorption bands as expected for a donor-acceptor type polymer, at 408 and 745 nm. In addition, polymer has excellent switching properties with satisfactory optical contrasts and very short switching times. Outstanding optical contrast in ...
Processable and multichromic polymer of bis-3-hexylthiophene substituted 4-tert-butylphenyl quinoxaline Ozyurt, Funda; Günbaş, Emrullah Görkem; Durmus, Asuman; Toppare, Levent Kamil (Elsevier BV, 2008-06-01) A new polythiophene derivative, poly-2,3-bis(4-tert-butylphenyl)-5,8-bis(4-hexylthiophen-2-yl)quinoxaline (PHTQ) was synthesized by both chemical and electrochemical polymerization and its electrochemical properties were reported. The monomer was electrochemically polymerized in the presence of tetrabutylammonium hexafluoropbosphate (TBAPF(6)) as the supporting electrolyte in dichloromethane-acetonitrile (5:95, v:v). Nuclear magnetic resonance (H-1 NMR) and Fourier transform infrared (FTIR) were utilized fo...
