在这项研究中，我们用飞行时间(TOF)技术研究了一系列同系三苯的双极载流子在同向异性区域的输运性质。观察到双极电子载流子输运，正、负电荷载流子迁移率都随着烷基链长的增加而减小。除了C4OTP外，负电荷载流子输运也观察到了离子导电性，烷基链长没有明显的依赖关系。合理地发现，电子跃迁过程中的正负电荷载流子迁移率都受柱内有序的影响。
In this study, ambipolar charge carrier transport properties were investigated for a homologous series of triphenylene by time-of-flight (TOF) technique for the homeotropic domains. Ambipolar electronic charge carrier transport was observed and the both positive and negative charge carrier mobilities decrease with the increase of the alkyl chain length. Ionic conduction was also observed for the negative charge carrier transport except for C4OTP and any remarkable dependency of the alkyl chain length was not seen. It was reasonably found that both the positive and negative charged carrier mobilities by electronic hopping process is affected by the intra columnar order.
