DESCRIPTION:The use of just two types of building blocks\, linear and angul
 ar\, in conjunction with symmetry considerations allows the rational desig
 n of a wide range of metallocyclic polygons and polyhedra via the coordina
 tion motif.1-3 We have used this approach to self-assemble a variety of 2D
  supramolecular polygons such as triangles\, rectangles\, squares\, hexago
 ns\, etc. as well as a number of 3D supramolecular polyhedra: truncated te
 trahedra\, triginal prisms\, cubooctahedra4 and dodecahedra.5 An example o
 f the methodology is illustrated in Figure 1.\n\n \n\nMore recently\, we h
 ave functionalized these rigid supramolecular scaffolds with different ele
 ctroactive\, host-guest\, dendritic (Figure 2)\, and hydrophobic/hydrophil
 ic moieties and have investigated the properties of these multifunctionali
 zed supramolecular species.6 Additionally\, we have begun to explore the s
 elf-assembly of 2D polygons and 3D polyhedra on a variety of surfaces with
  the aim of developing their potential to be used in device settings.7-10 
 These novel\, supramolecular ensembles are characterized by physical and s
 pectral means. The design strategy\, formation\, characterization and pote
 ntial uses of these novel metallocyclic assemblies will be discussed\, alo
 ng with our recent results in crystal engineering.\n\n \n\nReferences\n\n1
