Similarly to polyaniline and polythiophene, several other self-doped conducting polymers have been explored including polypyrrole, poly(3,6-(carbaz-9-yl) propanesulfonate), poly(p-phenylene), poly(indolecar-boxylic acid), polyphenylenevinylene, and poly(2-ethynyl-N-(4-sulfo-butyl)pyridinium betaine). The details of synthesis and properties are described in the following sections. 

Reynolds et al. [54] reported the electrochemical synthesis of self-doped, water-soluble, N-propanesulfonated poly(3,4-propylenedioxypy-rrole). The sulfonated monomer, N-propanesulfonate-substituted 3,4-propylenedioxypyrrole (N-PrS PProDOP) was prepared by treating 3,4-propylenedioxypyrrole with NaH in dry tetrahydrofuran and 1-propanesulfonate as shown in Figure 5.10. The poly(N-PrS PProDOP) films were synthesized in a mixture of propylene carbonate and water (94 6) with supporting electrolyte LiC104 in the potential range —0.4 to... 

The reports on electrochemical synthesis of self-doped sulfonated polypyrroles in aqueous media are limited in comparison with nonaqueous media. The first report on the synthesis of copolymer poly(pyrroleco-(3-(pyrrol-l-yl)propanesulfonate)) films in aqueous media for ion exchange was by Rajeshwar et al. [56]. The copolymer films were prepared without...

Poly (thiophene)s are of particular interest as electfochromic materials owing to their chemical stability, ease of synthesis and processability. For the most part, current research has been focused on composites, blends and copolymer formations of several conjugated polyheterocyclics, polythiophene and its derivatives, especially PEIX)T. In one example, poly(3,4-ethylenedioxythiophene) (PEDOT)/poly(2-acrylamido-2-methyl-l-propanesulfonate) (PAMPS) composite films were prepared by Sonmez et al. for alternative electrochromic applications [50]. Thin composite films comprised of PEDOT/PAMPS were reported to switch rapidly between oxidized and neufial states, in less than 0.4 s, with an initial optical contrast of 76% at A.max. 615 nm. Nanostructured blends of electrochromic polymers such as polypyrrole and poly(3,4-ethylenedioxythiophene) were developed via self-assembly by Inganas etal. for application as an electrochromic window [26]. Uniir etal. developed a graft-type electrochromic copolymer of polythiophene and polytetrahydrofuran for use in elecfiochromic devices [51]. Two EDOT-based copolymers, poly[(3,4-ethylenedioxythiophene)-aZ/-(2,5-dioctyloxyphenylene)] and poly[(3,4-ethylenedioxythiophene)-aft-(9,9 -dioctylfluorene)] were developed by Aubert et al. as other candidates for electrochromic device development [52],...

The first report of a completely chemical synthesis of P3TASs was given by Ikenuoe et al. who synthesized poly(i-(3-thienyl)propanesulfonate) [8]. In their proce-... 

An oxidative polymerization of aniline in the presence of poly(2-acrylamido-2-methyl-l-propanesulfonic acid) (PAMPSA) as a template was described in Reference 124. The process was carried out in water, and ammonium persulfate was used as initiator. The synthesis was performed at room temperature. In similar conditions, but with benzenesulfonic add instead of AMPSA, polymerization of aniline does not occur. According to the authors, the localization and protoni-zation of aniline takes place along the chain of AMPSA. Adding sodium chloride to the reaction solution, considerably decreased in both the process rate and the polyaniline yields. What was interesting was that the system remained phase-homogeneous on all stages of conversions. Kinetics examination lead to the condusion that the process is of a pronounced autocatalytic character. Electroconductivity of the film formed from polyaniline-PAMPSA complex has rather low conductivity of about 10 S cm . ...
