Zusammenfassung:The redox behavior is markedly different for the second generation dendrimer 1 (depicted on the right) from that of the first generation dendrimer without the densely packed dendritic structure. The unusually positive FeIII/FeII redox potential of 1 in water (+0.19 V vs. SCE) is attributable to the strong shielding of the heme core from the surrounding solvent by the dendritic environment.
