“…Sakmeche 24 reported on polybithiophene and poly(3,4-ethylene dioxythiophene), which were achieved via electropolymerization in aqueous SDS solutions on a Pt electrode. In our research, we found out that 3-octyloxythiophene could also be polymerized in a similar medium because the oxidation potential of 3-octyloxythiophene is similar to that of bithiophene and 3,4-ethylene dioxythiophene.…”

“…It has been found that thiophene and its derivatives (e.g., 3,4-ethylene dioxythiophene and bithiophene) can also be electropolymerized in acid or sodium dodecyl sulfate (SDS) aqueous solutions. 23,24 In this article, we report on the synthesis and characterization of a kind of monosubstituted poly(3-alkoxythiophene) to study its electrochemical redox behaviors and electrochromic properties. Interestingly, the alkoxythiophene monomers were found to be partially soluble in aqueous solution containing electrolyte when SDS was added as a surfactant, and they could be electrochemically polymerized to yield a polymer with electrochromic properties, which possessed solubility in common organic solvents.…”

Poly(3-n-octyloxythiophene), a conjugated polymer, which possessed solubility in common organic solvents, was synthesized by electrochemical polymerization in the presence of lithium perchlorate as the supporting electrolyte and sodium dodecyl sulfate as the surfactant in an aqueous medium. Characterizations of the intermediate, monomer, and polymer were performed by NMR spectroscopy, Fourier transform infrared spectroscopy, ultravioletvisible spectroscopy, and gel permeation chromatography. The process of electrochemical polymerization and the electrochemical redox behaviors were investigated by cyclic voltammetry and the potentiostatic method. A poly(3-noctyloxythiophene) film that was deposited on a platinum electrode was found to exhibit electrochromic behaviors, and it switched electrochemically between blue-green oxidized and dark red reduced states.

“…This explains why PEDOT appears to be among the most stable organic conducting polymers currently available. Several studies have shown that conducting polymers such as polythiophene and derivatives could be easily electropolymerized in water and aqueous micellar solution on platinum [10,16,17], copper [18], iron, aluminum and steel electrodes [7,16,17]. Water constitutes an ideal solvent for all applications, because of lack of toxicity, inexpensive product and non-pollutant properties.…”

“…Among those currently under study in our laboratory are poly(5-amino-1,4-naphtoquinone), 1 1 poly(5-amino-1-naphtol), 12 ester-substituted polyphenols, 13 and poly-(ethylene dioxythiophene) (PEDT). [14][15][16] The underlying idea of this study consists of the utilization of an electrooxidized conducting film to capture negatively charged ODN molecules in an electrochemical solution. We chose PEDT as the matrix polymer for the deposition of thin films on metal surfaces because it is easy to prepare homogeneous PEDT films by electropolymerization under mild conditions of pH and temperature.…”

Oligonucleotides were incorporated into conducting films of poly(3, 4-ethylene dioxythiophene) by an electrochemical method that involves two steps. The electrode is first coated with the polymer film by electropolymerization followed by electrooxidation of the formed polymer in the presence of the oligonucleotide. Neutral water soluble polymers such as poly(vinylpyrrolidone) or poly(ethylene glycol) were added to the polymerizing medium resulting in higher incorporation yields of oligonucleotides. The results showed that a payload of about 1.5 nmol/cm2 can be achieved in an 8 micron thick film for an oligomer concentration of about 70 microM in the working solution. Various physical methods were used to analyze the surface of the polymer-coated electrodes. Results showed the presence of domains of varying sizes at the film surface, corresponding to the insertion of the hydrophilic polymer within the matrix of the conductive polymer. The release of entrapped oligonucleotides from the coated film exhibited a three-step profile: a "burst" period during the first 5 min followed by an intermediate and a very slow release period lasting several days. Such polymer films could be exploited as useful reservoirs of biologically active substances for in vivo delivery to targeted tissues. For example, coated stents that can release antiproliferative agents such as antisense oligonucleotides at the site of balloon dilatation may be of interest in the treatment of postangioplasty restenosis.
