Abstract

We synthesized liquid crystalline 2-phenylbenzothiazole derivatives and investigated their charge carrier transport properties by time-of-flight experiments. These materials show less ordered phases such as smectic A, smectic C, and nematic phases at temperature range lower than 100° C, and their mobility was relatively small, from 10− 5 cm2/Vs to 10− 4 cm2/Vs. In addition, the mobility depends on temperature, while it did not depend on ...
