• Subject Area: Experimental Condensed Matter Physics ; Inorganic Molecular Chemistry - Synthesis and Characterisation ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry

The aim of the project is to expand the field of spintronics of lanthanide(III) single molecule magnets (SMMs) within quantum devices by molecular design and to allow the read out of its quantum state. In particular, we focus on the engineering of the intrinsic spin-cascade, consisting of a ligand radical spin, the electronic spin and a hyper-fine coupled nuclear spin of the lanthanide metal ion, that enables to address the nuclear-spin based quantum register in quantum computing applications. Towards this goal, two series of radical-substituted Terbium (III) bis-phthalocyaninato and di-Terbium (III) tris-phthalocyaninato complexes with addition-ally peripheric organic SExt = 1/2 substituents will be synthesized and subjected to surface STM-studies.
