We have investigated the liquid crystalline behavior and charge carrier transport properties in the semectic phases of a terphenyl derivative, 4-4″-bis(dodecyloxy)-3-methyl-p-terphenyl (12O-TPMe-O12) having methyl side chain in the terphenyl core part. In its samples highly purified by recrystallization several times, we observed the transient photocurrents indicating electronic conduction not only
我们研究了具有甲基侧链的三联苯衍生物 4-4″-双(十二烷氧基)-3-甲基-对三联苯(12O-TPMe-O12)的近晶相中的液晶行为和电荷载流子传输特性。三联苯核心部分。在通过多次重结晶高度纯化的样品中,我们观察到瞬态光电流不仅表明空穴而且电子的电子传导,并确定它们在 SmC 和 SmG 相中的迁移率为 5 × 10−4 和 0.9 × 10−2 cm2/Vs , 分别。因此,我们得出结论,三联苯衍生物中电荷载流子传输的内在性质是电子和双极性的,其中可以传输电子和空穴。
