title: Formation and spectroscopic characterization of the dioxygen adduct of a heme-Cu complex possessing a cross-linked tyrosine-histidine mimic: modeling the active site of cytochrome c oxidase.
abstract: A binucleating porphyrin with covalently appended copper chelates having a cross-linked imidazole-phenol group as the novel active site model of cytochrome c oxidase has been prepared, and the dioxygen adduct of its iron(II)-copper(I) complex was spectroscopically characterized.
