“…[ 1 ] Introduction of sulfonic acid salts at the end of the side chains provided the solubility, and polymers employing the same principle for water solubility using different ions such as sulfonium, [ 2 , 3 ] pyridinum [ 4 ] or ammonium salts [ 5 , 6 ] and varying chain lengths have been reported and/or are commercially available.…”

“…Such covalently bonded substituents may also make the resulting polymer self-doped, 14 meaning that the required counter ion during doping is a side group of the polymer chain itself. Since the first watersoluble conducting polymers 14,15 were reported, water-soluble PEDOT derivatives have been enabled for example through poly(4-(2,3-dihydrothieno [3,4-b]- [1,4]dioxin-2-yl-methoxy)-1-butanesulfonic acid, sodium salt (PEDOT-S). [16][17][18][19] We recently demonstrated human epithelial cell detachment using a PEDOT-S:H thin film.…”

Water-soluble conducting polymers are of interest to enable more versatile processing in aqueous media as well as to facilitate interactions with biomolecules. Here, we report a substituted poly(3,4-ethylenedioxythiophene) derivative (PEDOT-S:H) that is fully water-soluble and selfdoped. When electrochemically oxidizing a PEDOT-S:H thin film, the film detaches from the under-laying electrode. The oxidation of PEDOT-S:H starts with an initial phase of swelling followed by cracking before it finally disrupts into small flakes and detaches from the electrode.We investigated the detachment mechanism and found that parameters such as the size, charge and concentration of ions in the electrolyte, the temperature and also the pH influence the characteristics of detachment. When oxidizing PEDOT-S:H, the positively charged polymer backbone is balanced by anions from the electrolyte solution and also by the sulphonate groups 2 on the side chains (more self-doping). From our experiments, we conclude that detachment of the PEDOT-S:H film upon oxidation occurs in part due to swelling caused by an inflow of solvated anions and associated water, and in part due to chain rearrangements within the film, caused by more self-doping. We believe that PEDOT-S:H detachment can be of interest in a number of different applications, including addressed and active control of the release of materials such as biomolecules and cell cultures.

“…Similarly polyfluoroalkyl substituted polythiophenes can be synthesized TM, while water-soluble, self-doped polythiophenes have been prepared by the introduction of ionic groups in the side chain [235][236][237][238]. Thiophene oligomers such as bithiophenes 239 and terthiophenes possess lower oxidation potentials than the thiophene monomers (1.05 V, 1.31 V, and 2.07 V (vs. SCE) for terthiophene, bithiophene and thiophene, respectively) 24° and are therefore more suitable for the electrochemical polymerization since this lower oxidation potential decreases the risk of over oxidation.…”

Recent progress in the synthesis and characterization of well-defined conjugated polymers and oligomers is presented. The different synthetic schemes for most of the important conjugated polymers will be discussed using a subdivision into three main sections, covering hydrocarbon polymers, heterocyclic polymers and the oligomers, respectively. Although the materials properties will be referred to, the main emphasis of the review is directed to the different strategies that are now available to produce conjugated polymers and welldefined oligomers in a reproducible way and with full control over most of the important macromolecular properties.
