“…This may point out that low molecular weight DATE oligomers or DATE terminal groups were absent, which may point out that low molecular weight DATE oligomers or DATE terminal groups were absent in the copolymer unlike the corresponding homopolymer PDATE. The thiophene trimer/monomer peak intensity ratio increased in the order PTh > P(DATEecoeTh) > PDATE (0.24 > 0.02 > 0.01) [15,18] confirming that the ratio is largest for the PTh homopolymer and smallest for PDATE as expected. Thus, it is obvious that polymerization of both monomers has taken place.…”

“…The most abundant product was BF 2 due to degradation of dopant for samples PDATE, PTh and their mechanical mixture [15,18]. For the mechanical mixture dopant/C 4 H 7 ratio was 4.8:1 whereas for the copolymer this ratio was decreased to 1:5.4, about 25-fold decrease (Fig.…”

“…Recent pyrolysis studies on electrochemically prepared polypyrroles and polythiophenes showed that thermal decomposition products due to cleavage of the aromatic ring were more abundant contrary to the chemically prepared samples [7][8][9]13]. In general, it may be thought that the cleavage of the aromatic ring will be preferential only if the polymer has a network structure.…”

“…Although several studies on thermal degradation of polythiophene appeared in the literature [5][6][7][8][9], there are only few studies on thermal stability of PMTh [2,10]. The thermal stability of PMTh films electrochemically doped with SnCl 5 À and SbCl 6 À anions was studied by thermogravimetric analysis, TGA.…”

In this study, pyrolysis mass spectrometry has been applied for the investigation of thermal characteristics of $\hbox{PF}_{6}^{-}$‐doped polythiophene (PTh) films. Thermal degradation of PTh showed behaviour identical with $\hbox{BF}_{4}^{-}$‐doped polythiophene (BF4‐PTh), indicating that the effects of the dopants in question on the thermal characteristics of the PTh are not significant. Besides the oligomer peaks (up to hexamer), peaks indicating decomposition of the thiophene ring have also been detected as in the case of BF4‐PTh. However, the data also indicated that the oxidation of the $\hbox{PF}_{6}^{-}$ dopant was much more effective, yielding mainly POF3, H3PO4 compounds even for the freshly prepared samples. Upon ageing, the yield of these products increased and exposure to air for more than 50 days also caused degradation of the PTh chains. Furthermore, substitution of the thiophene (Th) ring by fluorine has been recorded and was associated with reactions of Th with the reactive oxidation products of the dopant. Analyses of the de‐doped samples showed that although de‐doping was effective to a certain extent, inward diffusion of the counter ion (C4H9)4N+ has also occurred. This diffusion was more efficient than that was observed for BF4‐PTh samples. Copyright © 2004 Society of Chemical Industry
