Synthesis of triangular metallodendrimers via coordination-driven self-assembly
A new family of 60° dendritic di-Pt(II) acceptor tectons have been successfully designed and synthesized, from which a series of novel "three-component" triangular metallodendrimers were prepared via [3 + 3] coordination-driven self-assembly. The structur
Synthesis and characterization of dendritic platinum bisferrocenylacetylide complexes
A series of new dendritic platinum bisferrocenylacetylide complexes have been synthesized utilizing the coupling reaction of trans-Pt complexes with C-H bonds in alkynes as key steps. These new bimetallic dendrimers were fully characterized by multinuclea
Design and synthesis of 60° dendritic donor ligands and their coordination-driven self-assembly into supramolecular rhomboidal metallodendrimers
The design and self-assembly of novel rhomboidal metallodendrimers via coordination-driven self-assembly is described. By employing newly designed 60° ditopic donor linkers substituted with Frechet-type dendrons and appropriate 120° 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 metallodendrimers were characterized with multinuclear NMR (1H and 31P), 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.
