POLYMAG · Magnetic Coordination Cluster Polymers

Coordination polymers exhibiting magnetic properties can be considered as strategic and revolutionary materials due to their great potential in the development of ‘intelligent’ multifunctional materials including magnetic sensors and molecular spintronics precursors. The main goal of the proposed project “Magnetic Coordination Cluster Polymers” is the development on novel generation of functional materials via controlled assembly of coordination polymers based on polynuclear coordination clusters and multitopic linker groups, including organic radicals and redox-active polyoxoanions. In order to obtain coordination polymers a range of procedures and ligands will be explored. These synthesis procedures extend beyond those traditionally used and will include high-temperature reactions in the solid state and in high-boiling solvents, as well as novel solvothermal synthesis conditions offered by ultrasonic and microwave irradiation. The resulting coordination networks based on 1/2/3D linking modes will be characterized and investigated by modern physico-chemical methods in order to elucidate the relationship of their geometric and electronic/magnetic properties. The expected results will provide understanding of the role of gradually introduced inter-cluster coupling when moving from isolated molecules to multi-dimensional systems. The deliberate construction of extended magnetic networks is key to fundamental charge transport experiments in molecular spintronics and thus addresses scientific and societal needs regarding future low-energy information technologies and thus is of cross-disciplinary interest to groups in inorganic chemistry, condensed matter physics, and microelectronics.
