Phosphorogenic and spontaneous formation of tris(bipyridine)ruthenium in peptide scaffolds

Redox-active ruthenium complexes have been widely used in various fields; however, the harsh conditions required for their synthesis are not always conducive to their subsequent use in biological applications. In this study, we demonstrate the spontaneous formation of a derivative of tris(bipyridine)ruthenium at 37°C through the coordination of three bipyridyl ligands incorporated into a peptide to a ruthenium ion. Specifically, we synthesized...
