Abstract
The present invention concerns size- and shape-controlled, colloidal superparticles (SPs) and methods for synthesizing the same. Ligand-functionalized nanoparticles such as nonpolar-solvent-dispersible nanoparticles, are used, and the solvophobic interactions can be controlled. Advantageously, supercrystalline SPs having a superlattice structure, such as a face-centered cubic structure, can be produced. Further, the methods of the invention can provide SPs that self-assemble and are monodisperse. The SPs can be doped with organic dyes and further assembled into more complex structures.
