SP2: Preparation of spin coated thin films and self-assembled monolayers of magnetic transition metal complexes

A prerequisite for technological application of single molecule magnets (SMMs) is their conversion into ordered arrays on substrates. Magnetic trimetallic bis(oxamato) transition metal complexes as model systems of SMMs will be used for the formation of thin films by means of spin coating. By the functionalization of these complexes with terminal SH groups the formation of self-assembled monolayers (SAMs) will be performed as an alternative approach. The trimetallic complexes will be characterized by, for example, SQUID magnetometry, ESR, IR and Raman spectroscopy and thin layers by magneto-optical Kerr effect spectroscopy. It is essential to understand how a structural modification of the complexes (planarity, charge, functional groups such as, for example, the central N,N' bridging units or the terminal ligands) and the deposition conditions (solvent, substrate, and rotation speed for the spin coating process; SH-functionalized trimetallic species solely or in mixture with organic thiols for the SAM formation) will influence the molecular and the film properties. This knowledge will be used as a feed-back for the synthesis of new molecules with properties tailored to achieve desired magnetic, magneto-optic or spin polarized transport properties, which are processable for device fabrication.
