Abstract:
This thesis has focused on functionalising heterometallic [nPr2NH2][Cr7NiF8(O2CtBu)16], {Cr7Ni}, clusters, which are candidates for qubits in quantum information processing, by substitution of the peripheral carboxylic acids to produce [nPr2NH2][Cr7NiF8(O2CtBu)16-x(O2CR)], where R is a group with the desired functionality. The use of pyridyl and carboxylic acid containing groups has been investigated for the purposes of linking {Cr7Ni} units, either through metal sites and metallic clusters. The work has resulted in the synthesis of multi-component, polymetallic, nano-scale constructs where in some cases where the individual building blocks have been pre-synthesised and isolated prior to synthesis, with examples of three, four and six {Cr7Ni} units bound to a variety of metal clusters. A selection of aromatic functionalised carboxylic acids has also been successfully substituted onto the ring periphery with the prospect of binding to aromatic surfaces such as graphene and carbon nanotubes. These include fluorenylmethyloxycarbonyl protected amino acids, which opens a potential avenue to grafting of peptide chains to the periphery.
