Organized assemblies of magnetic clusters

In this work we have explored the possibilities to create layered organizations of the Mn₁₂ single-molecule magnets using the Langmuir–Blodgett technique or attaching these clusters onto a metal surface by preparing self-assembled monolayers (SAMs). In the first part we discuss the use of the Langmuir–Blodgett (LB) technique in order to obtain organized magnetic films formed by monolayers of these clusters. Two strategies have been used with this aim. The first one consists of mixing Mn₁₂ acetate or benzoate derivatives with an amphiphile, while the second procedure is based on the use of Mn₁₂ derivatives specifically designed to form LB films. An alternative method is that of preparing self-assembled monolayers (SAMs). Some preliminary results obtained with this method are reported in the second part of the work. To cite this article: M.
