The Cover Feature shows the anchorage of a dioxo-molybdenum complex to the bipyridine ligand of the MOF type UiO-67 (Zr). In addition, a post-synthetic exchange process of Zr for Ti was implemented to modify the photochemical properties maintaining the structure of the MOF. The dioxo-Mo anchored to UiO-67 allows the selective oxidation of a monoterpene (α-pinene or R-carvone) to the epoxide (100 %) by a photo-stimulated Oxygen Atom Transfer (OAT) process using molecular oxygen as an oxidant and UV-vis radiation. During the photo-induced OAT reaction, a Mo(IV) species is formed, and the catalytically active unit is regenerated through its interaction with O2 generating the oxoperoxo-Mo(VI) complex capable of transferring two oxygen atoms to the monoterpene under UV-vis light.
