Enhancing the Air Stability of Dimolybdenum Paddlewheel Complexes: Redox Tuning through Fluorine Substituents.

ABSTRACT: The optical and electrochemical properties of quadruply bonded dimolybdenum paddlewheel complexes (Mo₂PWCs) make them ideal candidates for incorporation into functional materials or devices, but one of the greatest bottlenecks for this is their poor stability toward atmospheric oxygen. By tuning the potential at which the Mo₂ core is oxidized, it was possible to increase the tolerance of Mo₂PWCs to air. A series of homoleptic Mo₂PWCs bearing fluorinated formamidinate ligands have been synthesized and their electrochemical properties studied. The oxidation potential of the complexes was tuned in a predictable fashion by controlling the positions of the fluorine substituents on the ligands, as guided by a Hammett relationship.
