Several poly(3-acylpyrrole)s have been studied by cyclic voltammetry. The influence of some common impurities like water and cyanide present in the solvent-electrolyte system on the redox behavior of the polymer films were emphasized. Due to the presence of such impurities we have also observed changes in the macroscopic properties of the films such as their electrical conductivities. There is enough evidence that the amount of such impurities can be correlated to the degree of the so called overoxidation process.

Both anodically and cathodically coloring electrochromic polymer based on dithieno[3,4-b,3 ',4 '-e]-[1,4]-dithiine
Sahin, E; Camurlu, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01)
In this study poly(dithieno[3,4-b,3',4'-e]-[1,4]-dithiine) (PDTH) was synthesized potentiodynamically in both p- and n-doping domains in 0.1 M tetrabutylammonium tetrafluoroborate/acetonitrie/borontrifluoride ethylether (8:2, v/v). Resulting homopolymer was characterized via cyclic voltammetry, FTIR and UV-vis Spectroscopy. PDTH revealed both anodically and cathodically coloring electrochromic behavior, upon p-and n-doping, respectively. Spectroelectrochemistry analysis of p-doped polymer, reflected electro...
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...
Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT)
Kalay, Isil; Yigit, Deniz; GÜLLÜ, Mustafa; DEPCİ, TOLGA; Toppare, Levent Kamil; Hacioglu, Serife O. (Elsevier BV, 2020-09-01)
In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a carbazole comprising monomer; 9-(2-(4-(Phenyldiazenyl) phenoxy) ethyl)-3,6-di(thiophen-2-yl)-9H-carbazole (M1). Carbazole containing monomer (M1) and EDOT were combined with two different comonomer feed ratios, 1: 3 and 1: 5 respectively in order to investigate the effect of increasing EDOT amo...
A bis-selenophene substituted alkoxy benzene derivative as a highly stable novel electrochromic polymer
Udum, Y. Arslan; Tarkuc, S.; Toppare, Levent Kamil (Elsevier BV, 2009-03-01)
Up to date there are few studies reporting the use of selenophene derivatives as electrochromic polymers. This report highlights the synthesis of a selenophene containing multi-ring aromatic polymer which possesses reasonable optical contrasts at both visible and near-IR regions. Electrochemical synthesis of a conducting polymer from a multi-ring aromatic monomer, 2-(2,5-bis(hexyloxy)-4-(selenophen-2-yl)phenyl)selenophene (BSB(OC6H13)(2)), was achieved at a lower potential than its corresponding parent, sel...
A CONDUCTING COMPOSITE OF POLYPYRROLE .1. SYNTHESIS AND CHARACTERIZATION
SELAMPINAR, F; Akbulut, Ural; YALCIN, T; SUZER, S; Toppare, Levent Kamil (Elsevier BV, 1994-02-01)
A conducting composite of polypyrrole was prepared via electrochemical methods. A polyamide was used as the insulating matrix polymer. The characterization of the composite was done by FT-IR, SEM, TGA, DSC and pyrolysis studies. Conductivity and solubility studies together with spectroscopic methods reveal that H bonding exists between the two polymers and a possible grafting to a certain extent.
