Synthesis of Six-Component Metallodendrimers via [3 + 3] Coordination-Driven Self-Assembly

摘要

A new class of 120° dendritic di-Pt(II) acceptor subunits hasbeen designed and synthesized, from which six-componenthexagonal metallodendrimers were easily formed with 120°dendritic dipyridine donors via [3 + 3] coordination-drivenself-assembly. The structures of all metallodendrimers areconfirmed by multinuclear NMR, ESI-TOF-MS/ESI-FTMS,and elemental analysis. MMFF force-field simulations indi-cates that all metallodendrimers have a hexagonal ring withan internal radius of approximately 1.4 nm.
