The design and self-assembly of novel rhomboidal metallodendrimers via coordination-driven self-assembly is described. By employing newly designed 60 degrees ditopic donor linkers substituted with Frechet-type dendrons and appropriate 120 degrees rigid di-Pt(II) acceptor subunits, a variety of [G-1] [G-3] rhomboidal metallodendrimers with well-defined shape and size were prepared under mild conditions in high yields. The supramolecular metalloden-drimers were characterized with multinuclear NMR (H-1 and P-31), mass spectrometry (CSI-TOF-MS), and elemental analysis. Isotopically resolved mass spectrometry data support the existence of the metallodendrimers with rhomboidal cavities, and NMR data were consistent with the formation of all ensembles. The shape and size of all rhomboidal metallodendrimers were investigated with the PM6 semiempirical molecular orbital method.
