Electroactive, Internal Anthraquinonoid Dendritic Cores(1).
The modification of the extended 1 --> 3 anthraquinonoid monomer 1 by substitution of the central aliphatic moiety with a more rigid, aromatic moiety has allowed the syntheses of the new branched building block 6 possessing multiple, internal redox sites. This monomer was used to generate the first tier, dendritic macromolecules 8 and 9, which incorporate different internal redox centers within the infrastructure as well as the traditional peripheral multifunctionality. Using cyclic voltammetry experiments, the electrochemical response and electronic interactions between the two electroactive sites (the anthraquinonoid and nitroaromatic moieties) of these dendritic constructs were explored.
