Abstract
Polyoxomolybdates of the type [{MoVIMoVI5O21(H2O)6}12{MoV2O4(L)}30](12+30n)–, also referred to as keplerates (Kps), are polyanionic nanocapsules bearing 20 {Mo9O9} pores connected to a central cavity by 20 channels. In solution, they can entrap cations in different sites of their porous structure (in the internal cavity, in the pores, or on the capsule surface) in equilibrium with cations free in solution. The porosity of Kps was previously exploited to prepare nanostructured potential contrast agents through the self-assembly of KpOAc or KpHPO4 (i.e., Kp with L = acetate or hydrogen phosphate) macroanions and Gd(III) cations in water, accompanied by stabilization with F-127 Pluronics. The strongly enhanced water proton relaxivity observed at 20 MHz was postulated to derive from the trapping of Gd(III) aqua ions by the nanocapsules. In the present work, 1H fast field cycling NMR relaxometry allowed this hypothesis to be verified on aqueous suspensions containing either KpOAc or KpHPO4 and Gd(III) in diffe...
