Synthesis, spectral and electrochemical investigations of bichromophoric pentads possessing tetraazaporphyrin and (bipy)2RuII/(phen)2RuII moieties.
Four (bipy)2RuII and (phen)2RuII moieties have been attached to the magnesium tepraazaporphyrin periphery by exploiting thioether coordination to obtain pentads 1 and 2 respectively. These molecules exhibit strong inter-chromophore electronic interaction as reflected by the changes in their spectral and oxidation potential shifts.
