We present here the design and synthesis of a series of multicomponent supramolecular architectures, structures formed by the PdII/PtII-directed integrative social self-sorting in aqueous media of pairs of complementary N-monoalkyl-4,4′-bipyridinium/2,7-diazapyrenium-based ligands. Out of the different potential outcomes of the processes, we have found out how the designed systems selectively enhance the production of pseudo[1]rotaxanes, hermaphroditic host–guest aggregates that maximize the strength of the occurring π–π, C?H???π, and hydrophobic interactions, as well as the number of those interactions per receptor. It is also demonstrated how both integrative social and narcissistic PdII-directed self-sorting can occur orthogonally and concomitantly for this type of ditopic ligands.
