Surface chemistry of carboxylato-substituted metal oxo clusters - Model systems for nanoparticles

Clusters can be model systems for nanoparticles with regard to the chemistry of surface groups. Metal oxo clusters with carboxylato ligands are easily accessible and therefore well-suited for investigating the chemistry of cluster-bonded ligands. This review article gives an account on issues like ligand dynamics, post-synthesis ligand exchange, stability of the cluster core during ligand exchange, possible mechanisms of intra- and intermolecular ligand exchange or utilizing functional ligands.
