In order to obtain the high efficiency of electronic devices,a novel technique to align the columns of the discotic liquid crystals (DLCs) is strongly required,by which one can obtain the alignment perpendicular to the electrode surface (“face-on”) for the photovoltaic cells and light emitting diodes,or parallel to the isolator surface (“edge-on”) for the field effect transistors.However,the conventional techniques applied to nematic phase are not useful for the alignment control of highly ordered columnar phase of discotic liquid crystals.
