This presentation will focus on the shape-controlled synthesis and assembly of anisotropic nanoscale building blocks. Semiconductor nanocrystals, metal nanoparticles and nanorods, and rare earth doped lanthanide nanophosphor plates create a library of shape-controlled nanoparticles to explore fundamental assembly processes.  Shape directed assembly at the nanoscale allows both single component systems and collections of complementary shapes to be explored.  Experimental procedures for the synthesis and structural characterization of monodisperse nanospheres, nanorods and nanoplates and assemblies of these will be shared.  Specific examples of binary self-assembly of two and   three anisotropic nanoparticle building blocks mediated by shape complementarity will be presented as a case studies.  We will focus on liquid interfacial assembly techniques that allow the formation of self-assembled single component as well as the formation of binary superlattices from two anisotropic nanocrystals over a micrometer length scale and discuss progress on templated assembly of smaller discrete structures.  Recent efforts to explore periodic and aperiodic structures will also be shared.<br/>
