J. Briers et al., MOSSBAUER-SPECTROSCOPY OF FECL3-DOPED POLY(P-PHENYLENEVINYLENE) AND OF I-2-DOPED POLY(2,5-THIENYLENEVINYLENE), Journal of physical chemistry, 99(34), 1995, pp. 12971-12974
Mossbauer spectra of FeCl3-doped poly(phenylenevinylene) with composit
ion [C8H6(FeCl4))(0.30)](n) and of I-129(2)- doped poly(2,5-thienylene
vinylene) with composition [C6H4SI0.40](n) showed FeCl4- and symmetric
al I-5(-), respectively, to constitute the dopant ions. The above dopi
ng processes are in these aspects equal to the doping processes in pol
yacetylene, while the corresponding processes in polyphenylene (FeCl3
doping) and polythiophene (I-2 doping) show a slightly different behav
ior.
