Fig. 10. (a) Self-assembly of homoleptic and heteroleptic cages from shape-complementary ligands 14 and 16. Combining the two ligands with PdII or mixing their homoleptic cages leads to clean integrative self-sorting to give a cis-heteroleptic cage product; (b) 1H NMR titrations of the heteroleptic cage with ‘straight’ and ‘bent’-shaped di-sulfonate guests. Reproduced with permission from ref. 61.
