The proposal defines the synthesis and full physical characterisation of Single-Molecule Magnets (SMMs). These are molecules that behave as nanoscale magnets and thus have potential applications in information storage and quant computing. One of the most important goals in this new area of chemistry is the synthesis of SMMs that function above liquid nitrogen temperatures. This proposal outlines three new strategies for the synthesis of such molecules: 1. Usir triangles as molecular bricks. Cages made from triangular units are more likely to produce complexes with high spin ground states than those derived from dimers or monomers, and linking these units into rods, wheels, sheets, tetrahedra and octahedra using tripodal ligands should result in large cages with high spin. 2. Extracted metal fluorides. This is top-down approach to cage synthesis via breaking up an extended lattice structure leading to the isolation of extrer large metal units (>20 metals); the resultant complex may contain ions in high and/or unstable oxidation states; react is dependent upon the lattice energy of the mineral - an unusual synthetic control. Many mineral lattices can be studied 3. Giant tunable magnets. There are no examples where indivdual SMMs have been joined together to make 'giant' magnets. However if possible they would represent a huge step forward in the search for SMMs which function at ml higher temperatures. This proposal outlines, firstly, the dimerisation of SMMs and secondly, the building of larger,.more complicated arrays of SMMs whose properties may be tuned using specific building blocks.
