oriented para-aminophenyl groups in 2 facilitate the
formation of self-assembled monolayers on gold surfaces and
thus provide a viable molecular platform for charge
transport studies of magnetically functionalized
polyoxometalates. The title systems were isolated and
characterized in the solid state, in aqueous solutions, and
on metal surfaces. Using conducting tip atomic force
microscopy, the energies of {Co9(P2W15)3} frontier molecular
orbitals in the surface-bound state were found to directly
correlate with cyclic voltammetry data in aqueous solution.},
