Abstract

The resonance Raman spectra of SO3-doped poly(p-phenylenevinylene) (PPV) with two different electrical conductivities of 1 and 10 S cm-1 have been observed and analyzed by referring to the data of the radical cations of the model compounds. Both SO3-doped PPV films with electrical conductivities of 1 and 10 S cm-1 are considered to contain positive polarons having a more or less uniform lengths. The difference in the formation of polarons on the two sides of the doped film, i.e., one shiny side and the other dull side, is observed.
