近年來有機半導體逐漸被應用在小尺寸的行動裝置顯示器上，但如何使有機半導體元件效率提升是許多學者一致努力的方向，其中一項重要參數為材料的載子遷移率，因此如何提高載子遷移率及發展雙載子傳遞速度匹配的材料是研究學者的重要目標。
　　本論文藉由飛行時間量測法 (Time of Flight，TOF)探討一系列新開發的有機半導體材料的載子遷移率，此系列材料為三氮唑吡啶 (Triazolopyridine)之衍生物。此系列材料結構同時含有具傳遞電洞特性的三苯胺 (Triphenylamine)分子或咔唑 (Carbazole)分子與具傳遞電子特性的三氮唑吡啶 (Triazolopyridine)基團，以飛行時間量測法鑑定後確認此系列材料皆具有雙載子傳輸特性，在電場強度為3.3×10^5 至8.6×10^5 V ⁄cm區間，電子遷移率介於8.4×10^-5至5.4×10^-4 cm^2/Vs區間，電洞遷移率介於7.3×10^-4至1.5×10^-4 cm^2 /Vs區間" ，此論文亦同時探討此系列材料的立體結構與載子傳輸特性的相關性。

Organic semiconductor materials have been gradually apply to small-size mobile displays in recent years. To further improve the efficiency of organic devices, one of the most important work is developing the materials with bipolar carrier-transporting properties.
In this thesis, carrier transport properties of a new series of organic materials have been studied by time-of-flight (TOF) method. Those materials are triazolopyridine derivatives. Triphenylamine or carbazole moiety are also conducted for hole-transporting capability, and triazolopyridine is conducted for electron-transport capability. All the materials in this thesis show bipolar carrier transporting property. The mobilities of electrons are between 8.4×10^-5 to 5.4×10^-4　cm^2/Vs in the electric field between 3.3×10^5 to　8.6×10^5　V⁄cm. The mobilities of holes are between 7.3×10^-4 to　1.5×10^-4　cm^2/Vs in the electric field between 3.3×10^5 to　8.6× 10^5　V ⁄cm. This thesis also discusses the relationship between the molecular structure and the carrier transporting properties of those materials.
