Abstract

Abstract: The synthesis and characterization of a series of iron and cobalt" picnic basket" porphyrins are described. Dioxygen binding to iron and cobalt picnic basket porphyrins has been studied by lH NMR and oxygen affinity measurements. These iron and cobalt picnic basket porphyrins bind dioxygen reversibly at room temperature with high affinities. The oxygen affinity increases as the basket size decreases. This effect indicates that a ...
