| Several ruthenium-edta complexes were synthesized and their optical and electrochemical properties studied. The reduction potential for the (edta);Bipyridine derivatives and their bis-bipyridyl ruthenium monomeric and dimeric complexes were also synthesized, and their optical and electrochemical properties studied. Electron-withdrawing substituents on the bipyridine rings caused absorption spectra to shift to lower frequencies and reduction potentials to more positive values. The solvent dependence upon these properties varied quantitatively with the solvent donor number. RR spectra of (bpy)... |
