An overall perspective of research in our laboratories based on functionalized nanomolecular rational design and construction that integrates the spatial arts, mathematics, and material science will be presented. Discussion encompasses the supramolecular paradigms of chemically and geometrically complementary building blocks, along with balanced thermodynamic metal-ligand parameters, to generate new materials via a one-step assembly process. Towards these goals, the incorporation and utility of the 2,2':6',2�-terpyridine scaffold provide an excellent avenue to complex, preprogrammed, macromolecular architectures. Thus, terpyridine rigidity, metal connectivity, and well-developed substituent chemistry have allowed the construction of materials predicated on similar, as well as dissimilar polytopic ligands. Progress from simple ring structures based on 120�- and 60�-juxtaposed bisterpyridines to the logical combinations of multiple, polytopic terpyridine building blocks, exemplified by the nearly quantitative synthesis of spoked-wheel architectures (Figure 1), will also be discussed. The structural implications of reaction concentration on the assembly process will be considered, especially where forming labile coordinative bonds and more thermodynamically favored products are concerned. The construction of novel 3D architectures will be demonstrated.
