Completely new materials arise when semiconductor nanoparticles are periodically ordered in superlattices. First pioneering preparations of such superlattices were achieved by self‐organization of ligand‐stabilized CdSe and CdS nanoparticles. The block polymerization to give micelles in the presence of gold salts and their reduction by the electron beam of a transmission electron microscope (TEM) led to ordered gold clusters. The picture on the right shows a TEM image of a material of this type.
