Abstract

Broadband dielectric spectroscopy has been employed to study the electric charge transport and molecular dynamics in columnar stacks of liquid crystalline phthalocyanine derivatives, materials which are of interest as one‐dimensional semiconductors or as photoconductors. Three relaxation processes and a conductivity contribution have been identified and it is concluded that the solid‐to‐liquid crystalline phase transition has no influence on the temperature dependence of the conductivity.
