The use of just two types of building blocks, linear and angular, in conjunction with symmetry considerations allows the rational design of a wide range of metallocyciic polygons and polyhedra via the coordination motif. We have used this approach to self-assemble a variety of 2D supramolecular polygons such as triangles, rectangles, squares, hexagons, etc. as well as a number of 3D supramolecular polyhedra: truncated tetrahedral, triginal prisms, cubooctahedra, dodecahedra as well as metallapolymers.<br/>More recently we have functionalized these rigid supramolecular scaffolds with different electroactive, host-guest, dendritic, and hydrophobic/hydrophilic moieties and have investigated the properties of these multi-functionalized supramolecular species. Additionally, we have explored the self-assembly of 2D polygons and 3D polyhedra on a variety of surfaces with the aim of developing their potential in device settings. These supramolecular ensembles are characterized by physical and spectral means. The design strategy, formation, characterization and biomedical activities of these assemblies will be discussed, along with our very recent results.
