摘要：

The electrical conductivity of molecular-weight-controlled poly(3-octylthiophene) is investigated. The molecular weight affects the electrical conductivity and elongation ratio to break. The elongated films show the anisotropy in conductivity. The linear dependence of log sigma against T-1/4 is observed on the plots in all directions of measurement. The conductivity increases with the square of elongation ratio for high-molecular-weight poly(3-octylthiophene). The multiplier constant reduces with decreasing molecular weight, which is explained by considering the internal slip of the conducting elements.
