Heptacene (1) has been produced via a monoketone precursor, 2, which was prepared from 1,2,4,5-tetrabromobenzene in nine steps in a total yield of 10 %. Compound 2 was converted to 1 quantitatively by heating at 202 °C. Heptacene exhibited high thermal stability in the solid state without any observable change over two months. To investigate the potential value of 1 as a material for p-type organic
七苯 ( 1 ) 已通过单酮前体2 生产,该前体由 1,2,4,5-四溴苯分九步制备,总产率为 10%。通过在 202 °C 下加热,化合物2定量转化为1。七苯在固态下表现出高热稳定性,两个月内没有任何可观察到的变化。为了研究1作为 p 型有机场效应晶体管 (OFET) 材料的潜在价值,通过将1真空沉积到六甲基二硅氮烷 (HMDS)/SiO 2 /Si 衬底上来制造顶部接触 OFET 器件。最佳空穴迁移率性能为 2.2 cm 2 V -1 s-1。这是在有效设备中使用稳定七苯并检查其电荷载流子特性的第一份报告。
