Synthesis, Characterization, and Electrochemical and Photophysical Properties of Rhenium(I) and ruthenium(II) complexes of 2,2′‐bipyridine ligand functionalized β‐cyclodextrins

The synthesis, characterization, and electrochemical and photophysical properties of the ReI and RuII complexes of permethylated β‐cyclodextrins, functionalized on the primary face by a 2,2′‐bipyridine ligand, are reported. For comparison, model compounds, in which the cyclodextrin was replaced by a Me group, were also prepared and their properties investigated.
