PDb02 フタロシアニン誘導体ディスコティック液晶の光電流特性

抄録

The photoconductivity in liquid crystalline phthalocyanine derivatives was studied by means of the time-of-flight technique. The measurements were performed for two phthalocyanine derivatives at various temperatures. The transient photocurrent with a plateau region was observed only in the discotic tetragonal phase of the H-phthalocyanine derivative. For that condition, the charge carriers were confirmed to be holes and their mobility was evaluated to be 9 10^<-3> cm^3/V that is almost one-order larger than that of triphenylene discotic liquid crystals.
