EPR and ENDOR characterization of Fe and Mn containing spin systems of relevance to proteins, magnetic materials, and oxidation catalysts
EMSL Project ID
3053
Abstract
In collaboration with Mike Bowman we are interested in characterizing the fundamental spin systems associated with Fe and Mn containing coordination complexes of fundamental interest to our research in three distinct areasa) metal-pi radical-metal systems where an electroactive bridge is used to perform molecular level switching of magnetic order. This project falls in the area of molecular scale/nanoscale magnetic devices (quantum computing)
b) Fe and Mn containing oxidation catalysts where magnetic characterization will hopefully allow us to determine catalytic structure activity relationships. Of particular interest is an Fe based alcohol oxidation catalyst where a spin state change may help explain certain reactivity profiles across a family of related catalytically active species, and a Mn based catalase mimic which we suspect is dimeric in active form
c) the development of magnetic spin/relaxation labels for determining protein substructures by NMR. We have prepared and crystallographically characterized an Fe-lysozyme complex which we hope to obtain fundamental details about the spin state and g tensor through frozen solution and single crystal EPR experiments
