Around a decade ago it was proposed that molecular magnets could be used as qubits for quantum information processing [1, 2]. The most studied targets involve preparation of two level systems as possible qubits – either S = 1/2 molecules or by using the ground mJ doublets of a lanthanide centre [2]. We are pursuing chemistry to link together heterometallic rings to make large supramolecular structures that bring together multiple such potential qubits [3, 4]. We have shown that we can make supramolecular assemblies of hybrid organic-inorganic [n]-rotaxanes where the components of hybrid organic-inorganic rotaxane are the heterometallic octanuclear metallic wheels based on chromium(III) fluoride-carboxylate bridged [Cr7MIIF8(O2CtBu)16]– rings and the axle is an organic thread which act also as a template for formation of the heterometallic ring about this axle. This route has allowed us to make hybrid organic–inorganic [2]- and [3]-rotaxanes. Using functionalised ‘stoppers’ on the axles we can produce hybrid organic–inorganic [2]- and [3]-rotaxanes that can act as ligands. Then these polymetallic rotaxane-ligands can be used as building blocks (modules) for construction of various supramoleculal assemblies [5]. Routes too much larger structures will also be described which involve heterometallic rings acting as ligands or as parts of hybrid [n]-rotaxanes. Recently we have examined creating hybrid organic-inorganic rotaxanes featuring a new type of metallic wheels based on titanium(IV) oxo-carboxylate bridged [Ti7MIIIO8(O2CtBu)16]– rings [6]. We will also discuss building complex diamagnetic molecules as hosts for our multiple qubit arrays.
