Molecular architecture via coordination: self-assembly of nanoscale hexagonal metallodendrimers with designed building blocks.

The first self-assembly of nanoscale metallodendrimers that have a hexagonal cavity as a core via the directional-bonding approach is reported. All metallodendrimers were characterized by multinuclear NMR (1H and 31P), mass spectrometry (ESI-MS and ESI-FT-ICR), and elemental analysis.
