以苝酰亚胺为原料，通过温和的Suzuki偶联反应和空气光催化环化反应，合成了一类扭曲缺电子多环芳烃（PAHs）. X射线晶体学明确证实了扭曲的PAH结构轴承四个酰亚胺基团。这些扭曲的多环芳烃的物理和电子性质也进行了分析，显示出较高的荧光量子产率为86%和适度的电子迁移率为0.017 cm ~ 2 V ~（-1）s ~（-1）。
The synthesis of a class of contorted electron-deficient polycyclic aromatic hydrocarbons (PAHs) has been achieved by a one-pot bay annulation of perylene diimide involving a mild Suzuki coupling and subsequent air-mediated, ambient-light-induced photocyclization. X-ray crystallography unambiguously confirmed the contorted PAH structure bearing four imide groups. The photophysical and electronic properties of these contorted PAHs were also analyzed, showing a high fluorescence quantum yield of 86% and moderate electron mobility of 0.017 cm2V–1s–1.
