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