Coordination-driven self-assembly of supramolecular cages: heteroatom-containing and complementary trigonal prisms

The self-assembly of three nanoscopic prisms of approximate size 1 x 4 nm is reported. Tetrahedral carbon, silicon, and phosphorus were used as structure-defining elements in these coordination-based cages. A carbon-based assembly completes a pair of nanoscopic complementary 3-D structures. The formation of the structures is supported by multinuclear NMR, ESI FT-ICR mass spectrometry, and elemental analysis data.
