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，研究了杂苯的合成和排列控制。成功地合成了由苯/呋喃环和苯/呋喃/磷孔环组成的多种杂环化合物。此外，通过引入适当的取代基，可以控制固态中的分子排列。此外，还开发了具有液晶性质的杂苯二烯。通过液晶态排列分子可以有效地提高载流子的迁移率。

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.
