  • Abstract 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.
