SP1: Thin films of redox-active high-spin molecules

Single molecule magnets (SMMs) are currently considered for applications in spin electronics and information storage devices. In order to use such molecules in devices, it is essential to deposit and arrange SMMs on substrates for addressing purposes. In the present project novel high-spin molecules will be synthesized and the conditions under which they can be deposited onto surfaces without decomposition will be elucidated experimentally. Particular emphasis of the project will be put on: the targeted assembly of novel non-oxide based single molecule magnets using a modular approach, their deposition and arrangement on metallic (Au(111), Co), insulating (SiO2), and semiconducting surfaces (Si, GaAs), and film characterization by various techniques such as SQUID magnetometry, near-field techniques (AFM, STM), variable angle spectroscopic ellipsometry, high-field ESR, IR, Raman and magneto-optical Kerr effect (MOKE) spectroscopy.
