Obiettivo del progetto (Objective)
'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.'
Introduzione (Teaser)
EU researchers have developed a novel way of making functional materials by using the controlled assembly of coordination polymers. They have also increased current knowledge of new magnetic materials for future information technologies.
Descrizione progetto (Article)
Coordination cluster polymers exhibiting magnetic properties are important materials because of their potential in the development of intelligent multifunctional materials such as magnetic sensors. These polymers are built up from magnetic polynuclear coordination clusters.
However, the controlled integration of the individual cluster properties into those of the final, networked system represents multiple challenges. Solving these problems was the aim of the 'Magnetic coordination cluster polymers' (POLYMAG) project, funded by the EU.
The project's main objectives were the development of novel cluster-based materials with exceptional magnetic properties. Other project aims included examining the structural, magnetic and thermal properties of both the prepared clusters and the coordination polymers they were based on.
To achieve these goals, POLYMAG developed practical and broadly applicable approaches for the synthesis of clusters and cluster-based coordination polymers. These methods included the use of conventional solution chemistry and novel synthetic procedures.
Clusters and coordination cluster polymers that were produced by the POLYMAG project were investigated using a range of physicochemical methods so as to characterise their chemical composition and their structural and electronic/magnetic properties. A single-crystal X-ray diffraction analysis was used for the structural characterisation of all prepared materials.
By the end of the project, POLYMAG had developed a library of synthetic pathways, and provided an understanding of the correlation between the structure and properties of clusters and cluster-based polymer systems. Tailor-made polymer systems can be applied in numerous important fields such as catalysis, pharmaceuticals, and solid-state materials used in electronics, optics and telecommunications.
