Synthesis of Triangular Metallodendrimers via Coordination-Driven Self-Assembly

A new family of 60 degrees dendritic di-Pt(II) acceptor tectons have been successfully designed and synthesized, from which a series of novel threecomponent triangular metallodendrimers were prepared via [3 + 3] coordination-driven self-assembly. The structures of newly designed triangular metallodendrimers are characterized by multinuclear NMR (H-1 and P-31), H-1 DOSY NMR, mass spectrometry (CSI-TOF-MS), and elemental analysis. The shape and size of all supramolecular dendritic triangles were investigated with PM6 semiempirical molecular orbital methods.
