Optical Transitions and Photoconductivity in Oriented Trans-Polyacetylenenclude the interchain electronic coupling between zig-zag, dimerized polyenic chains. The results of the present model are compared with the experimental data on the pump anisotropy of the photocurrent.

A Microscopic Picture for Very High Conductivities in Polymersivity temperature dependence (including the peak sometimes seen at higher temperatures and localization effects at very low temperatures). This picture involves highly anisotropic metallic conduction (with intrinsic conductivities exceeding 10. S/cm) combined with fluctuation-induced tunneling through chain defects.

Early problems associated with insolubility and environmental stability still exist, but have been sometimes overcome for many potential applications. The prototype conducting polymer, pol

This is observed in the evolution of the soliton lattice from a periodic array of well separated kinks and antikinks to either a small amplitude bond-order wave or a
