Abstract:A unique lanthanide-based single-molecule magnet (SMM) has been synthesized through Salen and β-diketonate ligands, namely, Dy2(salen)2(TTA)4(OAc)2, H2salen = N,N'-ethylenebis(salicylideneimine), Htta = thenoyl(trifluoro)acetonate). Single crystals were achieved by solution diffusion at room temperature. The structure of the complex was determined by X-ray crystallographic studies and magnetic property was investigated. The two Dy(III) ions in the molecules are bridged by two acetate groups. The strong electron-withdrawing ligand HTTA leads to this novel dinuclear dysprosium single-molecule magnet with a relatively large energy barrier (>40 K). As expected for SMM-like behavior, an Arrhenius fit to the data gives an effective relaxation barrier of Ueff = 45.97 K with a pre-exponential factor of τ0 =5.07 × 10-8 s. | |||

Abstract:C70 clusters have been deposited as nanostructured films on optically transparent electrode (OTE) surfaces using an electrophoretic approach. Upon electrodeposition of platinum particles, these nanostructured C70 films show notable activity toward methanol oxidation. The dependence of methanol oxidation on the amount of Pt and C70 in a half-cell reaction demonstrates the role of [70]fullerene nanocluster as new form of carbon support. The C70 films have a better activity for methanol oxidation than C60 films have. | |||
