Electronic transport of photoinjected holes in high molecular weight linear polymers with silicon and germanium backbone is electric field dependent and thermally activated. At fixed electric fields, during both rate and step heating, the mobility ac

Electronic transport of photoinjected holes in high molecular weight linear polymers with silicon and germanium backbone displays a familiar pattern of electric field and temperature dependence similar to behavior already reported in a very diverse c

Photoexcited eh pairs in poly(1,6 heptadiyne) are studied by photoinduced absorption and photoluminescence spectroscopy. Most of the pairs quickly recombine; some form metastable neutral states. Resonant Raman scattering spectra reveal coexistence of

We have measured the photomodulation and Raman spectra of iodine doped cis and trans polyacetylene [CH(I3−)y]x. The solitonic photoinduced absorption (PA) band gradually disappears from the spectra consistent with the reduction of neutral solitons

Nearly metallic polyacetylene doped to the level, y, of -0.01 to 0.05 acceptors or donors per carbon has a high, “nearly metallic” conductivity yet susceptibility very much less than the metallic value. We present here the results of an extensive
