Abstract
We report a "ligand stripping" method for the creation of secondary structures of colloidal nanocrystals. Using iron oxide as an example, we demonstrate that the use of diols as "stripping agents" allows the controllable removal of the original capping ligands and induces aggregation of nanocrystals into well-defined clusters.
