用飞行时间法(TOF)研究了含低聚硅氧烷链的四甲撑双酰亚胺(PTCBI)衍生物在宽温度范围内的电子输运特性。在含有二硅氧烷链的PtCBI衍生物的有序柱状相中，室温下电子迁移率超过0.1 cm(2)V(-1)S(-1)。在含有三硅氧烷链的PtCBI衍生物的无序柱状相中，电子迁移率在室温附近达到10(-3)cm(2)V(-1)S(-1)量级。这些电子迁移率在室温附近与温度无关。然而，当温度降低到室温以下时，它们对电场的依赖性变得更大；这种行为可以用跳跃输运机制来描述。实验结果用一维无序模型进行了分析。
Electron transport characteristics in nanosegregated columnar phases of perylene tetracarboxylic bisimide (PTCBI) derivatives bearing oligosiloxane chains are studied over wide temperature ranges using a time-of-flight (TOF) method. In the ordered columnar phases of the PTCBI derivatives bearing disiloxane chains, the electron mobilities exceed 0.1 cm(2) V(-1) s(-1) at room temperature. In the disordered columnar phase of the PTCBI derivative bearing trisiloxane chains, the electron mobility reaches the order of 10(-3) cm(2) V(-1) s(-1) at around room temperature. These electron mobilities are temperature-independent at around room temperature. However, their dependence upon the electric field becomes larger when the temperature is lowered below room temperature; this behavior is described by a hopping transport mechanism. The experimental results are analyzed using a one-dimensional disorder model.
