Research Abstract

The dioxygen activation catalyzed by metallenzymes is important chemistry in terms of development of energy conversion catalysts. Elucidation of the dioxygen activation mechanism is highly desired to understand the design principle of the nature for the development of bio-inspired molecular catalysts. Thus functional heme models are used for the investigation of the dioxygen activation mechanism applying spectroscopic methods, providing fundamental insights into the biological mechanism which underlies the efficacy of the catalyst.
