Lead
Lay summary
The goal of this project is to obtain new magnetic materials by connecting small and nanosized clusters through adequate linkers and to examine the physical properties of both, the clusters and the coordination polymers. Several synthetic strategies will be used to ensure efficient magnetic coupling within the materials. The synthetic protocols will include high-temperature reactions of metal carboxylates in the solid state and in high boiling solvents as well as novel hydro(solvo)thermal, microwave and ultrasonic methods. A variety of magnetic measurements will be done in order to elucidate the magnetic coupling schemes of these compounds. Preferentially, the detailed analyses will be based on structural data gained from X-ray investigations.

Abstract

Coordination polymers exhibiting magnetic proper-ties can be considered as strategic and revolutionary materials due to their great potential in the devel-opment of ‘intelligent’ multifunctional materials, magnetic sensors and magnetic materials, in par-ticular as future spintronic devices where such mag-netic materials are contacted conducting logic elements. Engineering of such kind of inorganic-organic hybrid materials from cluster building blocks offers potential due to the advantage they present for the design of materials that can be tailored and targeted for specific applications.The main goals of the proposed project “Magnetic coordination polymers of the nanosized clusters” are to obtain new magnetic materials by connecting small and nanosized clus-ters using adequate linkers and to examine the physical properties of both metal clusters and coor-dination polymers based on them, looking for un-usual magnetic behaviour. In order to obtain magnetic coordination polymers, several design strategies and procedures will be used to ensure that efficient magnetic coupling is manifested in these materials. These procedures extend beyond those traditionally used in synthetic protocols, and will include high-temperature reactions of metal carboxylates in the solid state and in high boiling solvents, as well as novel hydro(solvo)thermal, microwave and ultrasonic syntheses of target com-plexes with polyfunctional ligands. The so obtained coordination polymers based on metallic clusters will be characterized and investigated by modern phys-ico-chemical methods in order to elucidate their composition, and their geometric and elec-tronic/magnetic properties. The results will be a major step forward in the preparation of solid-state coordination materials, for use in applications as diverse as quantum information processing and information storage devices, both timely relevant and intensely investigated topical areas.
