A novel hybrid nanomaterial is obtained by functionalizing gold nanoparticles with a tetrairon(III) single-molecule magnet containing two 1,2-dithiolane end groups, which promote aggregation of the Au nanoparticles. The presence of intact Fe4 molecules is proven by synchrotron-based Xray Absorption Spectroscopy and Xray Magnetic Circular Dichroism Spectroscopy, while a detailed magnetic characterization confirms the persistence of SMM behavior, thus opening interesting perspectives in the field of molecular spintronics.
