and atom economy, and shows good functional‐group compatibility as well as scale‐up potential. Mechanistically, the tandem reaction is proposed to involve a nucleophilic addition/ring opening/regiospecific C−H annulation/protodeauration sequence terminated by a Friedel–Crafts‐type cyclization. Photophysical studies of the products indicated violet‐blue fluorescence emission with quantum yields up to
                                    我们描述了一种新的,短而灵活的方法,该方法通过邻位
乙炔基联芳基作为试剂,通过

蒽基的π延伸对N掺杂的多环
芳烃(PAH)。该策略使用易于获得的起始原料,由于具有较高的步骤和原子经济性,因此非常简单,并且显示出良好的官能团兼容性以及扩大规模的潜力。从机理上讲,串联反应被提出涉及亲核加成/开环/区域特异性CH环化/原脱氢序列,该序列被弗瑞德-克拉夫茨型环化反应终止。产品的光物理研究表明,紫蓝色荧光发射的量子产率高达0.45。
