A MOSSBAUER SPECTROSCOPIC STUDY FECL3-DOPED POLYACETYLENE
1992
Mossbauer spectra of FeCl3-doped polyacetylenes [CH(FeCl3)y]x (y=0.010, 0.057) have been measured at temperatures of 300, 243, 208, 143, 108 and 80K, respectively. For the sample for y=0.010, only two doublets were observed at Room Temperature (RT) and a third doublet appeared when temperature decreased to 208K. However the RT spectrum of sample y=0.057 consisted of three quadruple-split doublets. The relative intensities of these three doublets, especially for the light doped sample, corresponding to charge transfer, changed with temperature.
