Please cite this article in press as: L. Astratine, et al., Characterization and electrochromic properties of poly(2,3,5,6-tetrafluoroaniline): Progress towards a transparent conducting polymer, Electrochim. Acta (2012) a b s t r a c tElectrochromic films of poly(2,3,5,6-tetrafluoroaniline) (PTFA) were formed on ITO substrates from aqueous solutions utilising perchloric acid (HClO 4 ) as dopant. Electrochemical and spectroscopic characterization of PTFA films was performed in background electrolyte and in solutions with the addition of tetrahydrofuran. When the PTFA film was removed from its growth medium, a significant decrease in the faradaic current was observed. The faradaic response increased on addition of tetrahydrofuran which facilitates ion movement through the polymer matrix. PTFA films deposited on ITO substrate were orange and light orange in the oxidized and reduced forms, respectively. The films were ca. 25 nm in thickness. In aqueous solution the films showed a porous structure with a non-uniform distribution of pore diameters. In the presence of tetrahydrofuran a less porous structure was observed.

“…Conductive polymers (CPs), which have many interesting optical and electric properties, have aroused tremendous research enthusiasm in past decades [17][18][19][20][21][22]. Water-soluble/dispersible CPs or precursors have been used for the multilayer build-up since the very early development stage of the electrostatic LBL self-assembly technique [6][7][8].…”

“…In literature, this strategy was applied for different CPs to improve the mentioned properties. [3][4][5][6][7][8] Due to outstanding electrochemical properties such as; low oxidation potential, good stability and low bandgap, EDOT is one of the excellent candidates for electrochemical copolymerization. 23 As a result, in this study copolymerization technique was applied to improve the electrochemical properties of this novel monomer (BIMN) by insertion of EDOT unit.…”

A novel monomer; 2-(3-nitrophenyl)-4,7-di(thiophen-2-yl)-1H-benzo [d]imidazole) (BIMN) was used for electrochemical copolymerization with 3,4-ethylenedioxythiophene (EDOT). Polymerization was achieved in acetonitrile (ACN)/dichloromethane (DCM) (1:1, 1:3 and 1:5, molar ratios) solution containing sodium perchlorate (NaClO 4 ) and lithium perchlorate (LiClO 4 ) mixture as the supporting electrolyte on an ITO electrode. The chemical structures of monomer and copolymers were characterized by nuclear magnetic resonance ( 1 H NMR) and scanning electron microscopy (SEM). The optical and electrochromic properties were investigated by UV-vis spectrophotometer and cyclic voltammetry, respectively. Combination of BIMN and EDOT provides lower oxidation potential, lower bandgap and higher optical contrast.
