Claim:
1. A superstructure consisting of octapod-shaped nanocrystals, of the same or different chemical composition, forming an ordered assembly of octapods, characterized in that the assembly is a three-dimensional (3D) assembly of side-by-side aligned linear chains comprising at least 20 octapods; the 3D assembly consisting of vertical stacks of n 2D planar assemblies of chains, with n greater than 1, with stacking direction perpendicular to the planes that contain the 2D assemblies, wherein each 2D assembly is made of m chains of octapods, with m greater than one, provided that up to n−1 of the n 2D planar assemblies may be replaced by single chains of octapods, wherein each chain is made of a number of octapods greater than zero.
