8‐dioxido‐1,4‐naphthoquinonato (donq) bridges, in the presence of pyrenyl‐containing dendrimers of different generations (P0, P1 and P2), affords the triangular prismatic host–guest compounds [Pn⊂Ru6(p‐cymene)6(tpt)2(donq)3]6+ ([Pn⊂1]6+). The host–guest nature of these systems, with the pyrenyl moiety being encapsulated in the hydrophobic cavity of the cage and the dendritic functional group pointing
