熔融的,扩展的π系统(例如较大的并苯和异并苯)是有机薄膜晶体管(TFT)的有趣化合物。线性催化稠合环的数量越多,并苯的稳定性越低。通过周围融合额外的环,可以显着提高稳定性。在这里,我们提出了一种简便的方法,即使用二硼酸化的二氢蒽作为前驱体,仅需两个步骤即可获得高芳烃二芳氮基稠合的per。这些化合物通过π堆积在晶态下表现出明显的堆积。有望通过真空升华制备p沟道TFT的候选器件显示出高达0.12 cm 2 V -1 s -1的场效应迁移率。
Fused, extendedπ‐systems such as larger acenes and heteroacenes are interesting compounds for organic thin‐film transistors (TFTs). The larger the number of linearly cata‐fused rings, the lower the stability of the acenes. By peri‐fusion of additional rings, the stabilities can significantly be increased. Here we present a facile approach to use a diborylated dihydroanthracene as precursor to get

An intramolecular oxidativeC(sp3)–H amination from unprotected anilines and C(sp3)–H bonds readily occurs under mild conditions using t-BuOK, molecular oxygen and N,N-dimethylformamide (DMF). Success of this process, which requires mildly acidic N–H bonds and an activated C(sp3)–H bond (BDE < 85 kcal/mol), stems from synergy between basic, radical, and oxidizing species working together to promote
