Abstract

Abstract: 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 (4 a ) was coordinated to [Ru(bpy)2 ] 2+ (bpy=2, 2′‐bipyridine) to prepare a luminescent and chromogenic complex, [Ru(bpy)2 (4 a )][PF]2, which provided the selective dual‐channel detection of Cu II ions. Abstract : Seek and bind : A series of new phenanthroline‐derived ditopic macrocyclic receptors with variable cavity sizes and nitrogen or nitrogen and oxygen donor sites are prepared through a palladium‐catalyzed amination reaction (see scheme; dba=dibenzylideneacetone). One receptor coordinates to [Ru(bpy)2 ] 2+ (bpy=2, 2′‐bipyridine) to give a selective dual‐channel sensor for Cu II ions.
