A series of ditopic macrocyclic receptors with variable cavity sizes, containing nitrogen or mixed (nitrogen-oxygen) donor sites and an externally directed 1,10-phenanthroline fragment, were prepared by means of a palladium-catalyzed amination reaction. A ditopic mixed NO-ligand (4a) was coordinated to [Ru(bpy)(2)](2+) (bpy=2,2-bipyridine) to prepare a luminescent and chromogenic complex, [Ru(bpy)(2)(4a)][PF](2), which provided the selective dual-channel detection of Cu-II ions.
