Abstract

A series of aryl ether dendrimer porphyrin complexes were synthesized by a convergent approach. Iron porphyrin encapsulated within a large dendrimer framework reversibly bound dioxygen in the presence of 1-methylimidazole, where the resulting dioxygen adduct survived for more than 2 months even in the presence of water and (also) exhibited a high durability toward carbonylation under carbon monoxide with a half-life as long as 50h. As a cytochrome c mimic, we also synthesized a water-soluble dendrimer zinc porphyrin with a negative-charged exterior surface ((-O₂C) ₃₂L₄PZn), which, upon mixing with a positive-charged electron acceptor such as methylviologen, formed a spatially separated donor-acceptor supramolecular assembly. Upon irradiation with visible light, a long-range photoinduced electron transfer occurred through the dendrimer framework at a rate constant of 2.6×109s^-1.
