有機半導體材料本身具有獨特的光學、電氣、以及光電元件上的應用，其中載子遷移率(mobility)為影響元件性能之重要參數，因此如何提高載子遷移率及發展雙極性傳輸材料為一項重要課題。
在 此論文，我們將藉由飛行時間量測法(Time of Flight，TOF)來量測一系列具三甲基苯硼與吩噻嗪基團之非晶態有機材料的載子傳輸特性。我們發現在一分子上同時導入三甲基苯硼與吩噻嗪基團的確使 材料具有雙極性之傳輸特性，而電子遷移率介於6.2×10-6－1.0×10-3 cm2/Vs，電洞遷移率介於3.2×10-6－8.8×10-5 cm2/Vs的範圍之間。值得一提的是，隨著單一分子內的吩噻嗪基團數量增加，反而提升的該系列材料電子的傳遞能力，在各自具有3個、2個、1個吩噻嗪基 團的三種不同分子，其在相同電場下所測得之載子遷移率各自為7.7×10-5 cm2/Vs 、2.8×10-5 cm2/Vs 、7.1×10-6 cm2/Vs 。
此系列材料都具有雙載子傳輸特性，故可用為有機發光二極體中的主體材料。

Organic semiconductors can be widely applied in optoelectronic devices benefiting on their unique optical and electrical properties. Carrier transport capability of the materials plays a critical role in the performances of organic optoelectronic devices. Therefore, the development of bipolar-transporting materials is an important topic.
In this thesis, we use time-of-flight measurement technique to study carrier transport properties of phenothiazine/dimesitylborane-based materials. The dimesitylborane and phenothiazine moieties was verified to introduce bipolar transport capability. The electron and hole mobilities of these materials are in the range of 6.2×10-6－1.0×10-3 cm2/Vs and 3.2×10-6－8.8×10-5 cm2/Vs, respectively. Interestingly, we found that the electron mobility was increased with the increasing number of phenothiazine moieties. The electron mobilities of the three materials which have three, two and one phenothiazine moieties are 7.7 × 10-5cm2 / Vs, 2.8 × 10-5cm2 / Vs and 7.1 × 10-6cm2 / Vs, respectively.
Because the series of materials have bipolar transporting capability, they can be applied in OLED as host materials.
