A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(perfluorophenyl)-2,5-di(2-thienyl)-1H-pyrrole (FPTPy). The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1-NMR) and fourier transform infrared (FTIR). Polymer of FPTPy was also synthesized via potentiostatic electrochemical polymerization in acetonitrile (AN)/NaClO4/LiClO4 (0.1 M:0.1 M) Solvent-electrolyte couple. Characterizations of the resulting insoluble polymer were performed by cyclic voltammetry (CV), FTIR, scanning electron microscopy (SEM) and UV-Vis Spectroscopy. Four-probe technique was used to measure the conductivities of the samples. Moreover, the spectroelectrochemical and electrochromic properties of the polymer film were investigated. In addition, dual type polymer electrochromic devices (ECDs) based on P(FPTPy) with poly(3,4-ethylenedioxythiophene) (PEDOT) were constructed. Spectroelectrochemistry, electrochromic switching and open circuit stability of the devices were studied. They were found to have good switching times, reasonable contrasts and optical memories.

Synthesis and characterization of conducting copolymers of succinic acid bis-(4-pyrrol-1-yl-phenyl) ester and their electrochromic properties Ertas, M; Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-05-07) A new dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and butanedioyl dichloride. Electrochemical behavior of this monomer, succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) was studied. Homopolymerization was achieved by chemical and constant Current electrolysis methods. Copolymerization of SM with thiophene was performed by constant potential electrolysis in acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) and dichloromethane (DCM)-TBAFB, solvent-electroly...
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...
Synthesis, Characterization and Optoelectrochemical Properties of Poly(2,5-di(thiophen-2-yl)-1-(4-(thiophen-3-yl)phenyl)-1H-pyrrole-co-EDOT) Turac, Ersen; Sahmetlioglu, Ertugrul; Toppare, Levent Kamil; Yuruk, Huseyin (Informa UK Limited, 2010-01-01) A new polythiophene derivative was synthesized by electrochemical oxidative polymerization of 2,5-di( thiophen-2-yl)-1-(4-(thiophen-3-yl) phenyl)-1H-pyrrole (TTPP). The structure of the monomer was evaluated by H-1-NMR and FT-IR. The polymer (P(TTPP)) and its co-polymer with 3,4-ethylenedioxythiophene (P(TTPP-co-EDOT)) were synthesized via potentiostatic electrochemical polymerization. The resulting polymers were characterized by cyclic voltammetry (CV), FT-IR, SEM and UV-Vis spectroscopy, and conductivity ...
Synthesis, characterization, and electrochromic properties of conducting poly(hexanedioic acid bis-(2-thiophen-3-yl-ethyl ester) and its copolymer with thiophene CAMURLU, P; Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-10-14) Hexanedioic acid bis-(2-thiophen-3-yl-ethyl) ester (HABTE) was synthesized via the reaction of 3-thiophene ethanol with adipoyl chloride. Resulting monomer was electrochemically homopolymerized in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, in acetonitrile/borontrifloride ethylether solvent mixture (8:2, v/v). Copolymerization in the presence of thiophene was achieved in TBAFB/AN. Resulting homo and copolymers were characterized via CV, FTIR, DSC, TGA, SEM, and UV-vis...
Synthesis of a regular polymer containing pseudo-polyether cages Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2005-04-20) A new compound consisting of 2-thienyl units linked by polyether bridge has been synthesized and its electrochemical polymerization was performed via constant potential electrolysis (CPE) in an electrolytic solution containing 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)) dissolved in CH3CN. Chemical polymerization was carried out using FeCl3 as oxidizing agent. It is found that both methods gave the same polymer product without any cleavage of the polyether bridge between thiophene (Th) rings. Al...
