We studied the synthesis of novel terpyridine scaffolds from poly-nuclear and hetero-aryl aldehydes by the multicomponent condensation reactions with various acetyl pyridine derivatives in the presence of ammonium hydroxide. We have synthesised highly substituted pyridine scaffolds by different poly-nuclear and heterocyclic molecules that are not easily accessed by conventional methods. Comparative studies of two different processes catalysed by potassium hydroxide and pyrrolidine have been performed and presented in this report. The structures of all the newly prepared terpyridine molecules have been well established by preforming various spectral analysis and single crystal XRD studies for selected molecules. This approach addressed some structural miscellany concerns currently facing in photo-luminescent chemistry, and the derived hybrid pyridines could be used as suitable precursors for the synthesis of related photo-luminescent systems. The prepared scaffolds as such and their d-block or f-block metal complexes and coordination polymers may provide an efficient candidate for photo-luminescent chemistry.

我们研究了在氢氧化铵存在下通过与各种乙酰基吡啶衍生物的多组分缩合反应，从多核和杂芳基醛合成新型三联吡啶支架。我们已经通过传统方法不易获得的不同多核和杂环分子合成了高度取代的吡啶支架。本报告对氢氧化钾和吡咯烷催化的两种不同工艺进行了比较研究。通过对选定分子进行各种光谱分析和单晶 XRD 研究，已经很好地建立了所有新制备的三联吡啶分子的结构。这种方法解决了目前在光致发光化学中面临的一些结构杂项问题，衍生的杂化吡啶可用作合成相关光致发光系统的合适前体。制备的支架本身及其 d 嵌段或 f 嵌段金属配合物和配位聚合物可以为光致发光化学提供有效的候选者。
