Abstract: Compounds with polyhedral borane moieties have demonstrated numerous unique properties for a variety of applications, including nanoelectronics, drug delivery vehicles, and live cell imaging. Polyhedral boranes are good pharmacophore analogs of carbocycles because polyhedral boranes are inherently insensitive to many undesirable enzymatic metabolic transformations typical for a majority of aromatic compounds. The defined shape, low molecular volume, and high 3D symmetry of the surface are useful for the application of the polyhedral borane scaffolds as universal and convenient spacers for the modular assembly approach with a controllable predisposition of peripheral groups.
