The first rational synthesis of a BN‐doped coronene derivative in which the central benzene ring has been replaced by a borazine core is described. This includes six C−C ring‐closure steps that, through intramolecular Friedel–Crafts‐type reactions, allow the stepwise planarization of the hexaarylborazine precursor. UV/Vis absorption, emission, and electrochemical investigations show that the introduction
描述了一种BN掺杂的苯并戊烯衍生物的第一种合理合成方法,其中中心苯环已被硼嗪核心取代。这包括六个C-C闭环步骤,这些步骤通过分子内Friedel-Crafts型反应,可以逐步平整六芳基硼嗪的前体。UV / Vis的吸收,发射和电化学研究表明,中央BN核的引入引起HOMO-LUMO间隙的急剧扩大,并且相对于其全碳同类物,其蓝移发射特性得到增强。
