Heterogeneous conduction

From the characteristics observed—constant and stable current levels, transitions between zero and nonzero current levels with a stochastic process on millisecond-to-second time scale, multiple and heterogeneous conductance levels, and selectivity of cations over anion—it can safely be concluded that the ion pair 1 constitutes single ion channels. The similarity of the activity with those of natural ion channels is fantastic and seems far beyond the expectation if one considers the simplicity of the molecular structure.

The picture of high-or polyacetylene as a heterogeneously conducting material, which was derived from the anisotropic conductivity and polarized optical reflectance data, is also supported by scanning electron microscopy studies. 

To conclude, high-a polyacetylene is a highly, but heterogeneously conducting material whose charge transport properties after doping appear to be still determined by...
