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.
将三配位硼引入共轭体系是当前有机电子领域的研究热点。在本研究中，合成了一种嵌入三配位硼的噻吩基双环芳香烯（BAE）作为一种新型含硼共轭体系。三配位硼与稠合噻吩环的结合使BAE结构呈现扭曲构象，导致其具有较低的最低未占分子轨道（LUMO）的窄能吸收。还对高度缺电子的嵌入硼BAE在有机场效应晶体管（OFET）中的应用进行了初步研究，结果表明其具有中等偏高的电子迁移率。
