Metal-organic frameworks (MOFs) made of earth abundant elements, that are able to drive chemical reactions with the use of light under ambient conditions are attractive candidates for organic photoredox catalysis. In this work, the light induced oxidation of hydroxamic acids to form oxazolidinone derivatives was explored using high-surface area reticular materials as solid-state photocatalysts. Under aerobic conditions a survey of photoredox active MOFs yielded up to 50% conversion of a molecular probe. Determination of the reaction quantum yields, reaction kinetics at various temperatures and inhibition studies support a proposed mechanism for the photo-oxidation and provide guidelines for the molecular design of photocatalytic materials.
