The subject of our research is the study of rigid dendrimer molecules, assembled on surfaces. Dendrimers are a class of molecule synthesized from repeating units such that the molecular topology is self-similar. A new class of geometrically rigid metallodendrimers has been synthesized recently by MacDonnell et al., and is enantiopure. These multinuclear molecules with Ru2+ centers are planar with D3 symmetry. We shall present AFM images of the self-assembled dendrimers on functionalized and patterned surfaces. Because these dendrimers are charged we can direct their self-assembly with electrostatic interactions at the surface. Theoretical, molecular mechanics and experimental support for this process will be described.
