Absorption spectra of charged oligo (phenylenevinylene)s: On the detection of polaronic and bipolaronic states


  • The authors thank Prof. N. Tyutyulkov (Sofia) for helpful discussions and Dr. A. Grezner (Marburg) for making availabie unpublished results.


Communication: The effective conjugation length of poly(phenylenevinylene) an important conducting polymer, can be estimated by extrapolation of the results of UV/VIS/NIR studies of the radical anions and dianions of the soluble, well-characterized oligo(phenylenevinylene)s shown in the figure. This information, in turn, is usefull in describing the mechanism of conduction in the polymer.
