Periodic Reporting for period 1 - RMTBRC (Redox-responsive Magnetic Materials based on Polynuclear Organometallics)

Teaser

Summary

This project involves the synthesis of redox-responsive magnetic materials based on metal clusters, with functionality arising from their highly unusual electronic and magnetic properties (giant spin states and slow magnetic relaxation). The multitude of oxidation states for the metal clusters (seven) results in a large variety of materials to be accessed. The project involves experts from France, UK and USA with complementary skills in synthesis, materials science and chemical physics in order to explore these novel materials as for use in charge- and data-storage.

Work performed

Supramolecular polymerisations were employed to link hexanuclear clusters exhibiting giant spin and slow magnetic relaxation. Novel coordination polymers and their constituent clusters were characterised structurally and electrochemically, and their magnetic properties were investigated by SQUID magnetometry. The charge, coordination chemistry and polymerisation behaviour was extensively explored. The fellow contributed to scientific research which resulted in publication (Chem. Sci. 2019, 10, 6304).

Final results

Polymeric cluster materials synthesised thus far will be subject to detailed investigation by magnetometry in the final stage of the project. These unusual polymers of repeat units with giant spin are likely to display interesting electronic and magnetic properties, and may be useful in future materials for use in charge- and data-storage.
