Summary on Grant Application Form |
|
The recent advances made in synthesising magnetic clusters, and the novel properties displayed by some of these cages, lead to a need for new characterisation techniques to examine single molecule magnets.This project will analyse magnetic spin states within magnetic clusters using elastic neutron scattering (INS) in collaboration with Professor H. U. Guedel (Bern, Switzerland).The first task is to synthesise perdeuterated ligands for stabilising these magnetic clusters. Thereafter perdeuterated magnetic clusters will be made in 5 - 10 gramme quantities. INS studies will be performed at the ILL in Grenoble, and finally theoretical studies will be carried out at Bern to interpret the results. Six immediate target molecules are :(i) A dodecanuclear nickle wheel with an S = 2 ground state;(ii) A Co24 cage which appears to be a single molecular magnet;(iii) A tetranuclear nickle cubane with an S = 2 or S = 4 ground state;(iv) A dodecanuclear nickle prison with an S = 8 ground state;(v) A decanuclear iron cage with an S = 23/2 groung state;(vi) A dodecanuclear cobalt wheel isostructural with (i) above.Further clusters will be made in a perdeuterated form, time permitting, which will alloy further INS studies.
