5-b]pyridine. Single X-ray crystallographic diffraction studies had shown that compounds had different types of heterodimeric, homodimeric π–π stacking, T-type stacking, and intermolecular hydrogen bonds which lead to nanostructure formation detected by scanning electron microscope. DFT calculation had also been performed to quantify heterodimeric π–π and T-stacking interactions. GRAPHICAL ABSTRACT
摘要 5-氨基-4-氰基-1-(苯基/对-取代苯基)咪唑与环烷酮的Friedländer型缩合是通过将混合物与无水氯化铝在干燥的1,2-二氯乙烷中的悬浮液回流以产生7-氨基-3-芳基(5,6)环烷基咪唑并[4,5-b]吡啶。单 X 射线晶体衍射研究表明,化合物具有不同类型的异二聚体、同二聚体 π-π 堆积、T 型堆积和分子间氢键,这导致扫描电子显微镜检测到纳米结构的形成。还进行了 DFT 计算以量化异二聚体 π-π 和 T 堆积相互作用。图形概要
