Chiral hydrogen-bonded supramolecular capsules: synthesis, characterization and complexation of C70

Two supramolecular nanocapsules were generated by multi-component self-assembly of the novel bisphosphoric acid (R,R)-6 with suitable bis- and trisamidines. The resulting chiral, hydrogen-bonded capsules are stable even in polar media and at low concentrations and can be employed for the binding of C-70-fullerene in solution.
