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 C70-fullerene in solution.
Branched non-covalent complexes between carboxylic acids and two tris(amidines)

Carboxylic acids and two tris(amidine) bases formed branched 3:1 complexes with high solubility in chlorinated and aromatic solvents, particularly when aromatic carboxylic acids with suitable solubilising substituents were used. Whereas N,N′-diethylamidine complexes 10 proved to be difficult to isolate, the respective imidazoline complexes 14 were easily purified by crystallisation. Association constants were determined for model bis(imidazoline) complexes to be about 103 dm3 mol-1 in the competitive solvent mixture CDCl3-CD3OD (97:3).
