The complexes of poly(ethylene oxide) with sodium polyiodide are electronic conductors. The level of conductivity at room temperature is 2 to 3 orders of magnitude greater than that of simple quaternary ammonium polyiodide salts. Raman spectroscopy indicates that the polyiodide species formed in the polymeric material depends upon the salt concentration in the polymer as well as the iodine to sodium ion ratio. High conductivity is associated with the appearance of a polyiodide species having a resonance-enhanced Raman feature at ca. 171 cm/sup -1/. A photovoltaic effect is observed when the polyiodide-containing polymer is sandwiched between indium-tin oxide glass and platinum electrodes and then illuminated through the ITO. The sign of the photoinduced potential indicates that the photovoltaic effect arises from a recombination of electrons from ITO with holes in the polyiodide valance bond.
