Au11 nanoclusters immobilized on an alumina surface have shown to be accessible to ligand sphere transformations by thiolates in an aqueous environment. In contrast to the same ligand exchange in solution, the number of metal atoms in the core is preserved. This enables modifications of the nanocluster’s structure and properties even after surface immobilization, e.g. by inducing photoluminescence through binding of fluorescent thiolates.
