A subtle interplay between the flexibility of the 2,2'-bipyridyl-based diamine and the denticity of the coordination domain formed upon self-assembly enabled the formation of four distinct topologies stabilised by [Ag⋅⋅⋅Ag] pairs. The reactions utilising 2,6-diformylpyridine resulted in the formation of silver(I)-stabilised molecular tweezer, trefoil knot, and Solomon link. The 1,8-naphthyridine-based dialdehyde promoted the formation of [2]catenanes and trefoil knot, demonstrating very close Ag⋅⋅⋅Ag distances. Two of the studied assemblies demonstrated interesting luminescent properties in the solid state.
基于2,2'-联吡啶的二胺的灵活性与自组装时形成的配位域的配位数之间的微妙相互作用，使得通过[Ag⋅⋅⋅Ag]对稳定形成了四种不同的拓扑结构。利用2,6-二甲酰基吡啶的反应导致形成了银(I)稳定的分子镊子、三叶结和所罗门链。基于1,8-萘啶的二醛促进了[2]连环烷和三叶结的形成，显示出非常接近的Ag⋅⋅⋅Ag距离。所研究的两种组装体在固态下表现出有趣的发光特性。
