Abstract

A series of complexes containing bis(2,2′-bipyridine)ruthenium(II) and neutral ancilliary “super donor” ligands were synthesized and characterized. Their structural, electrochemical, and photophysical properties were studied and compared to those of tris(2,2′-bipyridine)ruthenium(II) and some reference compounds. Their properties were also modeled by density functional theory calculations, and trends were found vs the nature of the basicity of the heterocycle attached to the saturated aliphatic guanidium moiety.
