Abstract
An iron(II) porphyrin/1-methylimidazole (Im) complex, covalently encap sulated within a large aryl ether dendrimer cage ((lm)(2)(LSP)Fe-II), shows reversible dioxygen-binding activity, in which the dioxygen addu ct ((lm)(L5P)(FeO2)-O-II) survives over a period of months even in the presence of water. (lm)(LSP)(FeO2)-O-II was highly reluctant to under go carbonylation upon exposure to a carbon monoxide atmosphere, where the half-life of (lm)(LSP)(FeO2)-O-II was as long as 50 hours.
