The design and synthesis of novel 3-D supramolecular dendrimers is described. Coordination-driven self-assembly of a 120° diplatinum acceptor and tritopic pyridyl donors bearing [G-0]–[G-3] Fréchet-type dendrons results in a series of supramolecular dendrimers under mild conditions, possessing a robust adamantanoid core of well-defined shape and size. The assemblies were identified using multinuclear (31P and 1H) NMR spectroscopy and electrospray ionization (ESI) mass spectrometry, as well as pulsed field gradient spin-echo (PGSE) NMR measurement together with computational simulations. Isotopically resolved mass spectral data support the existence of the [6 + 4] assembly of adamantanoid dendrimers, and the NMR results are consistent with the formation of these symmetrical assemblies. PGSE NMR measurements together with MMFF force-field modeling clearly reveal the structural feature of the 3-D supramolecular dendrimers with varying sizes.
