Three novel BN-embedded V-shaped polycyclic aromatic hydrocarbons with different π-conjugation lengths were designed and successfully synthesized. Their single-crystal structures were confirmed by X-ray crystallographic analysis, and it is found that the molecular stacking structure can be effectively tuned by extending the length of π conjugation. Meanwhile, owing to the unique V-shaped molecular geometry, they exhibit moderate host-guest supramolecular interactions with both fullerenes C and C.
设计并成功合成了三种具有不同π共轭长度的新型含硼氮的V形多环芳烃。通过X射线晶体学分析确定了它们的单晶结构，发现通过延长π共轭长度可以有效地调节分子堆积结构。同时，由于独特的V形分子几何结构，它们与富勒烯C和C都表现出适度的主客体超分子相互作用。
