Synthesis and Arrangement Control of Heteroacenes for High-performance Charge-transporting Materials

为了开发高性能的电荷传输材料，对杂苯的合成和排列控制进行了研究。合成了一系列由苯/呋喃环和苯/呋喃/膦环组成的杂苯化合物。此外，通过引入合适的取代基来控制分子在固体中的排列。此外，还开发了具有液晶性的杂二烯。通过液晶态的分子排列可以有效地提高载流子迁移率。

Synthesis and arrangement control of heteroacenes were investigated in order to develop high-performance charge-transporting materials. A variety of heteroacenes composed of benzene/furan rings and benzene/furan/phosphole rings were successfully synthesized. In addition, molecular arrangement in the solid state was controlled by introducing appropriate substituents. Furthermore, heteroacenes with liquid-crystal nature were developed. Molecular arrangement via liquid-crystalline state was found to be effective for higher charge-carrier mobility.
