Remote control of bipyridine-metal coordination within a peptide dendrimer.
The metal coordinating ability of a bipyridine ligand at the core of a peptide dendrimer was found to be controlled by the nature of amino acids placed at the dendrimer periphery, with coordination being promoted by anionic residues and inhibited by cationic residues; heterotrimers with mixed charges were preferentially formed.
