Abstract

The synthesis of a series of phosphine-functionalized dipodal macrocycles is described; prior co-ordination of a cation within the macrocyclic cavity regulates the ligand structure aiding formation of heterodinuclear complexes. ... Attachment of two side chains to a macrocyclic framework yields dinucleating ligands capable of binding metals both within the macrocyclic cavity and between the functionalized side arms. This generates a heterotopic ligand which may exhibit ...
