Solution-processable derivatives 4a–d of the novel diindeno[1,2-g:1′,2′-s]rubicene ring system have been prepared in three steps from 1,5-dichloroanthraquinone. Charge extraction by linearly increasing voltage measurements indicates that 4a–d have bulk mobilities <10–7 cm2 V–1 s–1. Consistent with these low mobility values, field-effect transistors fabricated from 4a–d show poor performance. X-ray
新的二茚并[1,2- g:1',2'- s ]红荧烯环系统的溶液可加工衍生物4a - d由1,5-二氯蒽醌分三步制备。通过线性增加电压测量来提取电荷表明4a - d的整体迁移率<10 –7 cm 2 V –1 s –1。与这些低迁移率值一致,由4a - d制成的场效应晶体管表现出较差的性能。X射线晶体学分析表明,在晶体状态下,化合物4b - d的分子 分子以阻碍π–π堆叠的方式堆积,从而防止了分子之间的强电子耦合,这对于高电荷迁移率半导体性能至关重要。
