The Interplay Between Component Denticity and Flexibility Promotes the Formation of [Ag^I⋅⋅⋅Ag^I]-stabilised Links and Knots.

ABSTRACT: 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]²⁺ 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^I⋅⋅⋅Ag^I distances. Two of the studied assemblies demonstrated interesting luminescent properties in the solid state.
