The synthesis protocol from Facci et al 48 was adopted. Fc12-Br was dissolved in a NaPF6 saturated 50/50 ethanol/water (v/v) solution, after which 1.2 molar equivalence of AgPF6 was added. The mixture was stirred for 5 min prior to the addition of dichloromethane for phase separation. The organic layer was then collected, dried over MgSO4, and concentrated via a rotary evaporator. To obtain the final product, the mixture was placed in an ice bath and recrystallized from 50/50 water/methanol, giving brilliant yellow platelets.
