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.
