Herein, we demonstrate a novel one‐pot synthetic method towards a series of boron‐doped polycyclic aromatic hydrocarbons (B‐PAHs, 1 a–1 o), including hitherto unknown B‐doped zethrene derivatives, from ortho‐aryl substituted diarylalkynes with high atom efficiency and broad substrate scopes. A reaction mechanism is proposed based on the experimental investigation together with the theoretical calculations
在此,我们展示了一种新颖的一锅法合成一系列硼掺杂多环芳烃(B-PAHs,1a - 1o),包括迄今为止未知的B掺杂氮烯衍生物,该方法由邻位芳基取代的二芳基炔烃合成,具有高原子效率和广泛的底物范围。基于实验研究和理论计算,提出了一种反应机理,其中涉及独特的 1,4-硼迁移过程。通过 X 射线晶体学、循环伏安法、紫外/可见光吸收和荧光光谱对所得台式稳定的 B-PAH 进行了彻底研究。进一步制备了基于1f和1k的蓝色和绿色有机发光二极管(OLED)器件,展示了B-PAHs在有机光电子学中的广阔应用潜力。
