Supramolecular assembly

    A supramolecular assembly or "supermolecule" is a well defined complex of molecules held together by inclusion compound), it is more often used to denote larger complexes of molecules that form sphere-, rod-, or sheet-like species. The dimensions of supramolecular assemblies can range from nanometers to micrometers. Thus they allow access to nanoscale objects using a bottom-up approach in much fewer steps then a single molecule of similar dimensions.
