In order to develop columnar discotic liquid-crystalline compounds with high charge transport ability, a pyrene derivative having a thiophene moiety in the side chains was synthesized and the physical and thermal properties were studied by POM, DSC, and XRD measurements. It was shown that an ordered hexagonal columnar (Col_<ho>) phase appears in the temperature range of more than 130 degrees showing the liquid crystalline phase is stable. The hole mobility determined by the time-of-flight (TOF) method was 4.8×10^<-3>cm^2V^<-1>s^<-1> in the Col_<ho> phase at 140℃.
