Solid State Architecture in LB Films: Towards a Magnetic Molecular Memory

Abstract

Supramolecular engineering in solution has already led to exciting results. The same challenge can be tried in the solid state. The Langmuir-Blodgett technique allows the positioning of organizates at the molecular level. The structural order obtained by sequential depositions of mixed or alternate monolayers can be increased by introducing possible reactivity between sets of molecules or sets of assemblies. This coupling of struture and reactivity has already given examples of solid state architectures and active machineries. Ordering molecules in the monomolecular plane is still a challenge. We describe here an example of 2D cooperativity in a molecular assembly which is the first approach towards a molecular magnetic memory.
