The systematic investigation of the adsorption phenomena of magnetic polynuclear metal complexes (for example, single-molecule magnets) on various substrate surfaces and thus of the generated molecule–surface interfaces is appealing and worthwhile, because it allows us to create necessary guidelines for the fine-tuning of the structure and composition of our molecular material and, in particular, the metal-ligand coordination bonds. In our research we focus on the synthesis and optimization of polydentate ligands with surface anchoring groups and their metal complexes (see Figure below). We aim to preserve the key magnetic characteristics and improve the thermal and redox properties of these compounds when attached to electrodes. The main goal is to engineer electrically accessible molecular qubits for future information technology.  Sulfur-based anchoring groups can be used as functional components of Schiff base ligands, carboxylic acids, amino alcohols, and other organic systems to modulate the molecule–surface interactions.
