for novel polyaromatic hydrocarbons (PAHs) for applications in the area of organic electronics remains unchanged. Diacenaphthopyrene represents a new PAH consisting of two acenaphthylene units connected by a pyrene bridge. The system is built up by Pd-catalyzed cross-coupling, followed by acid catalyzed cyclosiomerization to generate the pyrene moiety. The new fused scaffold is formed in the last step
有机电子领域对新型多环
芳烃(PAH)的巨大需求仍然没有改变。二
苊并
芘是一种新的多环
芳烃,由两个
苊单元通过
芘桥连接而成。该系统是通过 Pd 催化的交叉偶联建立的,然后通过酸催化的环化反应生成
芘部分。新的融合支架是在最后一步通过 CH 激活形成的,其产量令人信服。我们还合成了一种基于氮杂
芘的类似物。通过 UV-Vis 和 PL 光谱、CV 测量和 DFT 计算对两种迄今为止未知的 PAH 进行了详细研究。基于这些结果,评估了新结构的能力以及氮掺入的效果。
