Abstract
The authors report on room-temperature nondispersive hole transport in films of a discotic liquid crystalline hexa-

have been determined and results of field- and temperature-dependent measurements could be well explained within the concept of charge transport by hopping in a one-dimensional manifold of transport sites formed by the columns of the discotic liquid crystal.
