An octa-cationic core-shell dendrimer as a molecular template for the assembly of anionic fullerene derivatives

An assembly comprising the non-covalent binding of eight mono-anionic fullerene subunits to a polyaryl ether dendrimer with an octa-cationic tetra[bis(benzylammonium)aryl]silane core has been prepared via a straightforward anion exchange reaction. The assembled octa-fullero-dendrimer has been characterized by NMR and UV-vis spectroscopy and its molecular weight determined by size-exclusion chromatography coupled with low angle light scattering (LALLS) techniques.
