The incorporation of tricoordinate boron into conjugated systems is of current interest in the field of organic electronics. In this study, a tricoordinate boron-embedded thiophene-based bistricyclic aromatic ene (BAE) was synthesized as a new boron-containing conjugated system. The combination of tricoordinate boron and fused thiophene rings imposed the twisted conformation in the BAE structure, resulting in the narrow energy absorption with the low-lying LUMO. Preliminary studies on the application of the highly electron-deficient boron-embedded BAE to organic field-effect transistors (OFETs) were also performed, revealing its moderately high electron mobility.

具有三配位硼的噻吩基双双环芳族芳香烯：一种新型的n型半导体

在有机电子领域中，将三配位硼结合到共轭体系中是当前的关注点。在这项研究中，三坐标嵌入硼的噻吩基双三环芳香烯（BAE）被合成为一种新型的含硼共轭体系。三配位硼和稠合的噻吩环的组合在BAE结构中施加了扭曲的构象，从而导致低位LUMO的能量吸收狭窄。还进行了将高度缺电子的硼嵌入BAE应用于有机场效应晶体管（OFET）的初步研究，揭示了其适度的高电子迁移率。
